Abstract: A porous aluminum electrode has a porous layer formed by sintering aluminum powder on the surface of an aluminum core. The porous aluminum electrode, when subjected to a formation to a voltage of 200V or more, is boiled and then subjected to a first forming process in which formation is performed in an aqueous solution of ammonium adipate at a temperature of 80° C. or below and a second forming process in which formation is performed in a boric acid aqueous solution. When heat depolarization is first carried out, washing with water is performed for five minutes or more before heat depolarization; therefore, the porous layer is not destroyed.
