PROBLEM TO BE SOLVED: To provide aluminum foil for an electrolytic capacitor electrode which has a suitable corrosion loss in weight by AC etching, attains excellent capacitance and is suitable for an anode in particular. SOLUTION: The aluminum foil for an electrolytic capacitor electrode subjected to AC etching treatment has a composition containing aluminum having purity of≥99.9%, and containing≤100 ppm Fe,≤100 ppm Si, 0.1 to 2.0 ppm Pb, 5 to 50 ppm Cu, 0.1 to 1 ppm Ti, 0.4 to 5 ppm V and 0.4 to 5 ppm Zr, and the balance inevitable impurities, and is made into the foil by hot rolling and cold rolling.
