PROBLEM TO BE SOLVED: To provide an aluminium electrolytic capacitor which can significantly raise the charging/discharging resistance performance and ripple current resistance performance of the electrolytic capacitor. SOLUTION: An aluminium electrolytic capacitor formed by impregnating a capacitor element, which is formed by winding or laminating an anode foil connected electrically with an anode tab terminal and a cathode foil connected electrically with a cathode tab terminal via a separator, with an electrolyte for drive is characterized in that a deposited layer is formed by depositing valve metallic particles on the surface, which comes into contact with at least the separator, of the cathode tab terminal, the deposited layer is formed into a sponge shape, the deposit thickness of the deposited layer is set at 2.0 to 10.0μm and the particle diameter of the metal particles is set at 0.020 to 0.200μm.
