In this process, an organic acid immersion step of immersing the aluminum electrode in an organic acid aqueous solution containing dodecanoic acid, benzoic acid, propanedioic acid, butanedioic acid, (E)-2-butenedioic acid, 2-hydroxypropane-1,2,3-tricarboxylic acid, (E)-1-propene-1,2,3-tricarboxylic acid, or the like is carried out after a pure water boiling step and before a chemical formation step. In the chemical formation step, a phosphoric acid immersion step of immersing the aluminum electrode in an aqueous solution containing phosphate ions is carried out one or more times in the course of raising a film withstand voltage to a chemical formation voltage.
