Abstract

A capacitor that includes a conductive metal substrate having a high porosity portion and a low porosity portion with a porosity lower than that of the high porosity portion; a dielectric layer on the conductive metal substrate; an upper electrode on the dielectric layer; an upper extended electrode on one principal face of the conductive metal substrate and electrically connected to the upper electrode; a lower extended electrode on the other principal face of the conductive metal substrate and electrically connected to the conductive metal substrate; and insulating layer on the upper electrode at a position overlapping with the low porosity portion through the dielectric layer and the upper electrode.
