Capacitor having a plurality of minute internal electrode portions filled by a dielectric layer

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.
