ABSTRACT:
A capacitor comprises an anode foil, a cathode foil, and an intermediate layer interposed between the foils, the capacitor being impregnated with an electrolyte. The surface of the anode foil confronting the intermediate layer is formed with an oxide film. An insulator is provided to maintain at least the anode foil out of contact with the intermediate layer. The intermediate layer comprises a low density capacitor paper impregnated with an electroconductive fine powder such that one surface of the paper contacts the cathode foil with a small potential difference.
