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.
摘要翻译：公开的固体电解电容器具有作为固体电解质的导电聚合物，并且抗氧化剂基本上只包含在布置在导电聚合物表面附近的层中。该抗氧化剂用于阻止有机材料的氧化进程。首先制备具有不含抗氧化剂的导电聚合物的电容器元件，然后将该电容器元件浸入含有抗氧化剂的溶液中。因此，将高浓度的抗氧化剂引入导电聚合物中，以便仅基本上仅包含在导电聚合物表面附近的层中。由于通过仅将电容器元件浸渍在抗氧化剂溶液中可以引入抗氧化剂，所以无论进行聚合物形成的方法如何，该方法可以广泛地应用于电容器。导电聚合物内部的抗氧化剂浓度基本上为零，使得其导电性不受影响。

摘要： In a solid electrolytic capacitor which employs a conducting polymer as the solid electrolyte, a first solid electrolytic layer (3) consisting of a sole conducting polymer is formed by chemical polymerization on an oxide film (2) formed on the surface of an anode body (1). Next, a second solid electrolytic layer (4) consisting of a conducting polymer containing fine powder, obtained by chemical polymerization using a solution in which fine powder is dispersed in a reaction solution for chemical polymerization, is formed on the first solid electrolytic layer (3). The fine powder is harder than the conducting polymer. 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).

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.
