Abstract
A process is provided for producing an electrolytic capacitor element that can uniformly form a highly electrically conductive polymer having a nano thickness level on a nano porous anode element substrate and suitable for use in high-capacitance electrolytic capacitors used in emergency power supplies and backup power supplies in electronic equipment. An oxide film and an electrically conductive polymer film are formed by pulsed constant current electrolysis of a monomer for an electrically conductive polymer and a nanoporous valve action metal in an electrolysis solution comprising an ionic liquid.
