SOLID-STATE CAPACITOR AND ITS MANUFACTURING METHOD

PROBLEM TO BE SOLVED: To provide a solid-state capacitor which has superior electrical properties such as a leakage current or the like and high productivity. SOLUTION: A solid-state capacitor is composed of an anode foil 11 made of an etching foil and a dielectric oxide film 12 formed on the etching foil, an etched aluminum cathode foil 13 facing the anode foil 11, a high-molecular layer 14 of poor conductivity formed on the surface of the anode foil 11, and a conductive fine particle layer 15 provided between the anode electrode foil 11 and the cathode foil 13. By this constitution, an excellent solid-state capacitor having less variation in electrical properties such as a leakage current, ESR and the like can be obtained. COPYRIGHT: (C)2003,JPO
