摘要： A conductive terminal includes an inner electrode part, an opening edge electrode part, and a lateral electrode part. The inner electrode part is connectable to a terminal electrode of a chip component by being inserted along an inner wall of an accommodation recess of a case. The opening edge electrode part is formed continuously to the inner electrode part. The lateral electrode part is formed continuously to the opening edge electrode part along an outer surface of the case. The inner electrode part includes a base part, a curved part, and a continuous boundary part. The base part continues to the opening edge electrode part. The curved part is formed near a tip of the base part and protrudes away from the lateral electrode part. The continuous boundary part is formed between the base part and the curved part and continuously connects them.

摘要： A multilayer ceramic capacitor includes a stacked body and external electrodes. The stacked body includes stacked dielectric layers and internal electrodes. The external electrodes are disposed on lateral surfaces of the stacked body and are connected to the internal electrodes. The dielectric layers include outer layer portions and an effective layer portion. Each outer layer portion is adjacent to a corresponding main surface of the stacked body. Each outer layer portion is a dielectric layer located between a corresponding main surface and an internal electrode closest to the main surface. A ratio of a dimension of the effective layer portion in a stacking direction to a dimension of the stacked body in the stacking direction is not less than about 53% and not more than about 83%.

摘要： A multilayer ceramic capacitor that includes a ceramic body including a stack of a plurality of dielectric layers and a plurality of first and second internal electrodes; and first and second external electrodes provided at each of both end faces of the ceramic body. Each of the plurality of dielectric layers contain Ba, Ti, P and Si. The plurality of dielectric layers include an outer dielectric layer located on an outermost side in the stacking direction; an inner dielectric layer located between the first and second internal electrodes; and a side margin portion in a region where the first and second internal electrodes do not exist. In at least one of the outer dielectric layer, the inner dielectric layer and the side margin portion, the P and the Si segregate in at least one of grain-boundary triple points of three ceramic particles.

摘要： In a multilayer ceramic capacitor, an interposer includes, on a side of a first external electrode in a length direction, a first through conductive portion that penetrates the interposer in a stacking direction, and provides electrical conduction between a first joining electrode and a first mounting electrode. The interposer includes, on a side of a second external electrode in the length direction, a second through conductive portion that penetrates the interposer in the stacking direction, and provides electrical conduction between a second joining electrode and a second mounting electrode. The first joining electrode includes a first portion that covers a portion of a first interposer end surface on the one side in the length direction of the interposer. The second joining electrode includes a second portion that covers a portion of a second interposer end surface on the other side in the length direction of the interposer.
