Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor having proper electrostatic capacitance characteristics. SOLUTION: The solid electrolytic capacitor is provided with a capacitor element, constituted by winding an anode foil and a cathode foil with a separator holding a conductive polymer in between. Since an etching foil having a coating film composed of a metal carbide on its surface is used as the cathode foil, the electrostatic capacitance and ESR characteristics of the capacitor are satisfactory due to the proper continuity of the metal carbide.
