  • Solid electrolytic capacitor and method of manufacturing thereof
    Patent number: 8810997
    Abstract: A solid electrolytic capacitor with suppressed occurrence of short circuit is provided. The solid electrolytic capacitor includes an anode body having a surface on which a dielectric film is formed, and a conductive polymer layer formed on the dielectric film. The conductive polymer layer includes at least a first conductive polymer layer formed on the dielectric film and a second conductive polymer layer formed on the first conductive polymer layer. A silane compound in the first conductive polymer layer and the silane compound in the second conductive polymer layer have respective concentrations different from each other.
    Type: Grant
    Filed: June 21, 2012
    Date of Patent: August 19, 2014
    Assignees: SANYO Electric Co., Ltd., SAGA SANYO Industries Co., Ltd.
    Inventors: Nobuyuki Yamaguchi, Koji Fukuchi, Yasuhiro Tsunezumi
