Abstract
An ionic liquid formed of a cationic component and an anionic component characterized in that the cationic component contains fluorine atoms. When defects of an oxide film formed on the surface of a metal are anodized by a two-electrode system under existence of the ionic liquid, a current-voltage curve being obtained by applying a forward voltage from 0 V at a constant voltage rate of 1 V/s has an initial peak voltage and gives a withstand voltage of 50 V or above. This ionic liquid does not evaporate easily, exhibits hydrophobicity and low hygroscopicity, and has excellent metal oxide film-repairing ability.
