PROBLEM TO BE SOLVED: To provide an aluminum electrode foil for an electrolytic capacitor that combines excellent capacitance and superior processability. SOLUTION: The aluminum electrode foil for an electrolytic capacitor has an etching pit region and a dense region (1), and the dense region has a relative density of 1.2 to 1.6 times the etching pit region, and an absolute density of 2.0 g/cm<SP>3</SP>or above (2).
