摘要： The solid electrolytic capacitor disclosed has an electron donor organic compound layer of an organic compound provided between an oxide film as a dielectric and a conductive polymer layer and a conductive polymer layer as a solid electrolyte layer. In the step of forming the electron donor organic compound layer, the pellet on which the oxide film is formed, is caused to be exposed to vapor of the electron donor organic compound, and this enables the formation of a thin and uniform electron donor organic compound layer on the oxide film irrespective of the kind of electron donor organic compound. The pellet may alternatively be dipped in a solution of the electron donor organic compound. Where the dipping process uses silane coupling agent, aluminum coupling agent or titanium coupling agent, the thin and uniform electron donor organic compound layer can be formed by using alcohol solution or acidic solution of each coupling agent. The solid electrolytic capacitor having such a conductive polymer as a solid electrolyte is free from leakage current increase under high temperature condition.

摘要： A solid electrolytic capacitor free of short circuits which may be caused by the creeping of a solid electrolyte comprising a conducting polymer, and having high volume efficiency per volume. The solid electrolytic capacitor is constructed by successively forming an oxide film, a solid electrolyte (conducting polymer) and a cathode layer on an anode body which has an anode lead planted thereon. Then heating is applied, by a heater chip, to a part of the solid electrolyte that has crept from the head of the anode body along the anode lead to convert it is insulation, so as to produce a solid electrolyte insulated portion thereby. Or, in another way, the creeping solid electrolyte can be removed by heating with a heater chip and generating a thermal decomposition reaction thereof while supplying sufficient additional oxygen.
