PROBLEM TO BE SOLVED: To obtain aluminum alloy foil for the cathode of an electrolytic capacitor which can provide high electrostatic capacitance by suppressing coarse etching pits caused by large crystallized products, thereby forming a highly uniform etching pit distribution. SOLUTION: The aluminum alloy foil for the cathode of an electrolytic capacitor comprises, by weight, 0.05 to 0.30% Si, 0.22 to 0.60% Fe, 0.01 to 0.19% Cu and 0.21 to 2.0% Mn, and the balance Al with inevitable impurities.
