Abstract
A capacitor () includes a main body () in which dielectric layers () and electrode layers () are laminated, and an external electrode () connected to at least a part of the main body by metallikon. Each dielectric layer has a thickness Dt at a connection boundary () where the main body is connected to the external electrode, each electrode layer has a thickness Et at the connection boundary, and a ratio between the thickness Dt and the thickness Et is at least a first value DEmin. The first value DEmin may satisfy the following conditions with respect to a minimum set value Dt1 of the thickness Dt where a and b are coefficients.
