摘要： An element body of a rectangular parallelepiped shape includes a first principal surface arranged to constitute a mounting surface, a second principal surface opposing the first principal surface in a first direction, a pair of side surfaces opposing each other in a second direction, and a pair of end surfaces opposing each other in a third direction. An external electrode is disposed on the element body. The external electrode includes a conductive resin layer. The conductive resin layer continuously covers one part of the first principal surface, one part of the end surface, and one part of each of the pair of side surfaces. A length of the conductive resin layer in the first direction is smaller than a length of the conductive resin layer in the third direction.

摘要： A length in a first direction of an element body is smaller than a length in a second direction of the element body and smaller than a length in a third direction of the element body, the second direction being perpendicular to the first direction, the third direction being perpendicular to the first and second direction. A difference between a maximum thickness and a minimum thickness of a first electrode portion is smaller than a difference between a maximum thickness and a minimum thickness of a second electrode portion. A difference between a maximum thickness and a minimum thickness of a third electrode portion is smaller than a difference between a maximum thickness and a minimum thickness of a fourth electrode portion. The maximum thickness of the first electrode portion and the maximum thickness of the third electrode portion are larger than thicknesses of respective outer layer portions.

摘要： An element body of a rectangular parallelepiped shape includes a pair of principal surfaces opposing each other in a first direction, a pair of side surfaces opposing each other in a second direction, and a pair of end surfaces opposing each other in a third direction. An external electrode disposed on an end portion of the element body in the third direction. When viewed from the third direction, a width of the element body in the second direction is the largest at a central position in the first direction, and gradually decreases from the central portion in the first direction. When viewed from the third direction, a position in which a length from one end to another end of the conductive resin layer in the second direction is the largest is located closer to the one principal surface than the central position.

摘要： A length in a third direction of a first connection portion is smaller than a length in the third direction of a first main electrode portion. A length in the third direction of a second connection portion is smaller than a length in the third direction of a second main electrode portion. A thickness in a first direction of an inner layer portion is smaller than each of the length in the third direction of the first connection portion and the length in the third direction of the second connection portion and smaller than each of a gap from a second side surface to the first connection portion in the third direction and a gap from the second side surface to the second connection portion in the third direction. The second side surfaces oppose each other in the third direction perpendicular to the first direction.

摘要： A conductive resin layer includes a first region positioned on the end surface, a second region positioned on the side surface, and a third region positioned on a ridge portion between the end surface and the side surface. In a case where a maximum thickness of the first region is T1 (μm) and a maximum thickness of the second region is T2 (μm), the maximum thickness T1 and the maximum thickness T2 satisfy a relation of T2/T1≥0.11. In a cross-section along a thickness direction of the first region, a total area of voids in the first region is in a range of 5.0 to 36.0% of an area of the first region. In a cross-section along a thickness direction of the second region, a total area of voids in the second region is in the range of 5.0 to 36.0% of an area of the second region.

摘要： An element body of a rectangular parallelepiped shape includes a principal surface arranged to constitute a mounting surface, a pair of side surfaces opposing each other and adjacent to the principal surface, and a pair of end surfaces opposing each other and adjacent to the principal surface and the pair of side surfaces. An external electrode includes a sintered metal layer disposed on an end portion of the element body, and a conductive resin layer including a portion positioned on the principal surface and a portion positioned on the sintered metal layer. An end edge of the sintered metal layer is positioned closer to the end surface than a maximum thickness position of the portion positioned on the principal surface. A thickness of the conductive resin layer gradually decreases from the maximum thickness position to the portion positioned on the sintered metal layer.

摘要： An element body includes first and second end surfaces opposing each other in a first direction, first and second side surfaces opposing each other in a second direction, and first and second principal surfaces opposing each other in a third direction. The length of the element body in the third direction is shorter than that of the element body in the first direction and is shorter than that of the element body in the second direction. A pair of first external electrodes is disposed at both ends of the element body in the first direction. Each of the first external electrodes includes a first conductor part disposed on one main surface and a second conductor part disposed on the end surface and coupled to the first conductor part. The porosity of the first conductor part is smaller than that of the second conductor part.
