摘要： The solid electrolytic capacitor comprises a sealed capacitor element having, as a solid electrolyte layer, a heat resistant conductive layer formed on a dielectric oxide film. The heat resistant conducting polymer layer contains water, and the capacitor element inside is substantially oxygen-free. A cathode conductive layer is provided on the capacitor element and then both an external cathode lead and an external anode lead are mounted on the capacitor element. Water is supplied to the conducting polymer layer of the capacitor element such that the conducting polymer layer inside contains water. The capacitor element is then sealed such that water is held within the heat resistant conducting polymer layer and that the capacitor element inside is substantially oxygen-free. The step of supplying water is carried out by dipping the heat resistant conducting polymer layer in water or heavy water or exposed to water-containing inert gas. The capacitor element is sealed in a water-containing oxygen-free inert gas atmosphere. The resulting capacitor has excellent heat resistance.

摘要： The solid electrolytic capacitor disclosed has a conducting polymer as a solid electrolyte and an antioxidant contained substantially only in a layer disposed in the neighborhood of a surface of the conducting polymer. The antioxidant serves to block the progress of oxidation of organic materials. A capacitor element with conducting polymer not containing the antioxidant is first prepared and this capacitor element is then dipped in a solution containing the antioxidant. Thus, the antioxidant at high concentration is caused to be introduced into the conducting polymer so as to be contained substantially only in a layer disposed in the neighborhood of the surface of the conducting polymer. Since the antioxidant can be introduced by merely dipping the capacitor element in the antioxidant solution, the method can be applied widely to capacitors irrespective of the process of conducting polymer formation. The antioxidant concentration inside the conducting polymer is substantially zero so that the conductivity thereof is not affected.

With this arrangement, it is possible to prevent the application of a stress to the oxide film (2) by the solid electrolytic layer (4) consisting of a conducting polymer containing fine powder even if there is generated a stress at the time of curing of a molded resin (8).
