PROBLEM TO BE SOLVED: To provide aluminum alloy foil for an electrolytic capacitor cathode by which high electrostatic capacity is attained. SOLUTION: The aluminum alloy foil for an electrolytic capacitor cathode has a composition composed of, by mass, 0.01 to 0.15% Si, 0.01 to 0.15% Fe,≤0.005% Cu,≤0.001% Ti and 0.0005 to 0.0050% B, Ti/B≤0.5, 0.004-0.05% Ga, 0.006-0.1% in total of one, or two or more kinds of Na, In, Zn, Ni and Mg and the balance Al with inevitable impurities.
