  • Patent number: 9287051
    Abstract: A capacitor element includes an anode foil, the first oxide film on a surface of the anode foil, a solid electrolyte layer formed using ?-conjugated conductive polymer dispersing material on the first oxide film, and a cathode foil on the solid electrolyte layer. The cathode foil faces the first oxide film across the solid electrolyte layer. An electrolytic capacitor includes the capacitor element, an anode terminal connected to the anode foil, and a second oxide film on a surface of the anode terminal. The second oxide film provided on the anode terminal has higher water repellency than the first oxide film provided on the anode foil. This electrolytic capacitor can reduce a leakage current.
