Abstract
An electrolytic capacitor includes a capacitor element and an electrolyte solution. The capacitor element includes: an anode foil on which a dielectric layer is formed; a cathode foil which is opposite to the anode foil and on which an inorganic conductive layer is formed; and a conductive polymer layer that is interposed between the anode foil and the cathode foil, the conductive polymer layer including a conductive polymer. The cathode foil has a roughened surface on which the inorganic conductive layer is formed. And the conductive polymer layer is a layer formed with use of a dispersion or a solution containing the conductive polymer.
