Abstract
A capacitor that includes a substrate having a principal surface; a dielectric film on the principal surface of the substrate; and an electrode layer on the dielectric film. The substrate has a recess structure portion with at least one recess portion in a second region outside a first region where the electrode layer overlaps the dielectric layer when viewed in a plan view from a normal direction of the principal surface of the substrate, and the dielectric film is on the recess structure portion.
