Abstract
In the present invention, a capacitor element including a valve action metal, an oxide film layer formed on the surface of the valve action metal, and a solid electrolytic layer formed on the oxide film layer is provided with an organic compound having a boiling point of not lower than 150° C. and a melting point of not higher than 150° C., and the capacitor element including the organic compound is arranged inside a package. The oxide film is repaired with the organic compound as a solvent by an application of a dc voltage.
