The invention provides a high-capacity, long-life and low-ESR aluminum electrolytic capacitor having excellent short-circuiting resistance. Therefore, the aluminum electrolytic capacitor in the invention has a capacitor element in which an anode foil, a first separator, a cathode foil and a second separator are wound by being successively placed one over another so that the capacitor element is impregnated with a driving electrolytic solution and is stored in a metal case, and then, an open end of the metal case is sealed with a sealing material. Moreover, A ratio of B/A is set at 0.5-0.8, wherein, A is the total of the thicknesses of the first and the second separators prior to winding, and B is the total of the thicknesses of the first and the second separators after winding.
