Surface-mount thin-profile capacitor and method of producing the same
In a surface-mount thin-profile capacitor including an aluminum foil as a base member composed of an aluminum core and a pair of etched layers covering opposite surfaces of the aluminum core, a resist resin is formed at a boundary between an anode as each of opposite end portions of the aluminum foil and a cathode formed at a center area of each of opposite surfaces of the aluminum foil. The resist resin separates and isolates the etched layer on the side of the anode and a conductive polymer layer from each other. If a part of the conductive polymer layer climbs up onto the resist resin, the climbing part of the conductive polymer layer is covered with an additional resist resin.
