摘要 |
Disclosed is a solid electrolytic capacitor made of a structural body comprising a metal having a valve action, an oxide film formed on the surface of the metal, a semiconductor layer composed of a mixture of lead dioxide and lead sulfate, which is formed on the oxide film and, formed on the semiconductor layer, (a) a carbon layer, (b) a metal layer or (c) a carbon layer and a metal layer formed thereon. The semiconductor layer is formed by chemically depositing a mixture of lead dioxide and lead sulfate on the oxide film from a reaction mother liquid containing lead ions and persulfate ions. |
