  • Multi-layered solid electrolytic capacitor and method of manufacturing same
    Patent number: 7400492
    Abstract: A multi-layered solid electrolytic capacitor is furnished with a plurality of capacitor elements 6, each having an aluminum foil 1 having an anode portion 7 and a cathode portion 8 having a dielectric oxide film 2 and a cathode layer 3 successively formed on a surface of the aluminum foil 1. The capacitor elements 6 are stacked on each other. Adjacent anode portions 7 of the capacitor elements 6 are welded to one another and adjacent cathode portions 8 are electrically connected one another by a conductive paste layer 18. An insulative resin layer 16 is disposed on a boundary between the cathode portion 8 and the anode portion 7 of at least one of the capacitor elements 6 and on an adjacent region thereto.
    Type: Grant
