Abstract
A capacitor having a substrate, a first electrode layer, a dielectric layer, a second electrode layer, and first and second outer electrodes. The substrate has a first main surface and a second main surface opposite to the first main surface. The first electrode layer is on the first main surface of the substrate. The dielectric layer is on at least part of the first electrode layer. The second electrode layer is on at least part of the dielectric layer. The first outer electrode is electrically connected to the first electrode layer and the second outer electrode is electrically connected to the second electrode layer. At least one of the first electrode layer and the first outer electrode and the second electrode layer and the second outer electrode are in contact with each other at a first contact surface. The first contact surface includes a first uneven surface portion.
