Abstract
A sheet-shaped capacitor for storing electrical charges of large capacities, and to assure facilitated manufacture, cost reduction and improved reliability, and a method for manufacturing the capacitor. The capacitor includes a dielectric film 12, formed on a first major surface of a metal plate 11, an electrically conductive high polymer layer 13, formed on a first major surface of the dielectric film, and an electrically conductive layer 14 formed on a first major surface of the electrically conductive high polymer layer 13, such as by copper plating. A cathode electrode 20 is led out from the electrically conductive layer 14 on the side electrically conductive high polymer layer 13.
