This electrolytic capacitor is characterized by being provided with a capacitor element and an electrolyte. This electrolytic capacitor is further characterized in that the capacitor element is provided with: an anode foil on which a dielectric layer is formed; a cathode foil on which an inorganic conductive layer is formed, said cathode foil being opposite the anode foil; and a conductive polymer layer that contains a conductive polymer and is interposed between the anode foil and the cathode foil, wherein the surface of the cathode foil is roughened, the inorganic conductive layer is formed on the roughened surface, and the conductive polymer layer is formed using a solution or dispersion containing the conductive polymer. |
