ABSTRACT:
A solid electrolytic capacitor includes a capacitor element which includes an anode foil and a cathode foil rolled with a separator interposed therebetween, and a solid electrolyte layer or an electrically conductive polymer layer provided therein. The cathode foil is coated with a film of a metal nitride or a non-valve metal. The cathode foil has a smaller width than the anode foil, and the anode foil has substantially the same width as the separator.
