    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.

    摘要翻译： 固体电解电容器包括具有作为固体电解质层的形成在电介质氧化物膜上的耐热导电层的密封电容器元件。 耐热导电聚合物层含有水，并且内部的电容器元件基本上是无氧的。 在电容器元件上设置阴极导电层，然后将外部阴极引线和外部阳极引线安装在电容器元件上。 向电容器元件的导电性聚合物层供给水，内部的导电性高分子层含有水。 然后将电容器元件密封，使得水保持在耐热导电聚合物层内，并且内部的电容器元件基本上不含氧。 供水步骤是通过将耐热导电聚合物层浸入水或重水中或暴露于含水惰性气体中进行的。 电容器元件密封在含水无氧惰性气体气氛中。 所得电容器具有优异的耐热性。
