Abstract
A fluid dispersion obtained by mixing oxide particles and water is sprayed to a raw aluminum foil from a direction opposite to a travelling direction of the raw aluminum foil while the raw aluminum foil is allowed to travel. In this way, a roll-pressed mark of the raw aluminum foil is eliminated, and thus aluminum foil for aluminum electrolytic capacitor electrode is produced. Pyramidal-shaped recesses each having an acute angle tip are present all over a surface of the aluminum foil.
