ABSTRACT:
The present invention provides an electrolytic capacitor having a large capacitance sufficiently close to its design capacitance, and a method of easily producing such an electrolytic capacitor wherein a cathode-side conductive polymer layer of an electrolyzing electrode is formed on at least one side surface of an anode valve metal foil having through holes20and a coarsened surface, electrolysis is carried out in a conductive monomer solution, with the polymer layer used as the anode, and an electrolytically-formed conductive polymer layer is formed on the surface of the dielectric oxide film of the valve metal foil, thereby obtaining an electrolytic capacitor, whereby it is possible to easily obtain an electrolytic capacitor having a large capacitance sufficiently close to its design capacitance.
