The present invention provides an oxide film forming means on a metal surface, a repair means for an oxide film defect, a high performance electrolytic capacitor using the means, and an electrolyte thereof. It is a method of easily forming an oxide film on the surface of a metal or its alloy by anodizing using a solution containing an ionic liquid. As an application of this method, an ionic liquid, a solution in which salt is added to an ionic liquid, or a solution in which an ionic liquid is added to a conductive polymer or TCNQ salt is used as an electrolyte, and a valve metal or an alloy thereof is used as a metal. The electrolytic capacitor provided with the repair means of an oxide film defect can be comprised by methods, such as these. |
