Abstract
PURPOSE:To obtain an excellent solid electrolytic capacitor having a small equivalent series resistance value in a high-frequency band by forming a semiconductor layer between a foil on the cathode side and an oxide film layer. CONSTITUTION:In a solid electrolytic capacitor in which foil 8 on the cathode side and foil 9 on the anode side composed of valve metallic foil, the surface of which has an oxide film layer 13, are inserted and arranged so as to be respectively superposed in succession one by one alternately, a semiconductor layer 3 is formed between the foil 8 on the cathode side and the oxide film layer 11. Separators 10 are interposed between the foil 8 on the cathode side and the foil 9 on the anode side, and it is preferable that the semiconductor layer 3 consists of a mixture mainly comprising lead dioxide or lead dioxide and lead sulfate. Accordingly, the solid electrolytic capacitor having remarkably small equivalent series resistance in a high-frequency band and excellent performance is acquired.
