摘要： A capacitor includes a dielectric layer, a first external electrode layer, a second external electrode layer, a first internal electrode portion, a second internal electrode portion, and a close contact portion. The dielectric layer includes a first surface, a second surface facing the first surface, and a plurality of through-holes communicating between the first surface and the second surface. The first internal electrode portion is provided on a first through-hole portion. The second internal electrode portion is provided on a second through-hole portion. The close contact portion brings at least one of the first external electrode layer and the second external electrode layer into close contact with the dielectric layer, the close contact portion being provided on a third through-hole portion, the third through-hole portion being the remaining portion of the plurality of through-holes.

摘要： A multi-layer ceramic electronic component includes a ceramic body and an external electrode. The ceramic body includes a first side surface facing in a direction of a first axis, a second side surface facing in a direction of a second axis orthogonal to the first axis, a ridge that connects the first side surface and the second side surface to each other, and internal electrodes laminated along a third axis orthogonal to the first axis and the second axis and led out in a lead-out region. The external electrode includes a protrusion provided at a position along the ridge and protruding in the directions of the first axis and the second axis, and a first base portion and a second base portion extending from the protrusion along the first side surface and the second side surface, respectively, the external electrode covering the lead-out region.
