摘要：
There is provided an aluminum electrolytic capacitor comprising an anode, a cathode comprising aluminum and an electrolytic solution containing an onium salt of fluorine-containing anion, wherein the cathode has a peak top of A12p spectrum of 74.0 to 75.8 eV as measured by a method in which the surface of the cathode in the aluminum electrolytic capacitor heated at 125 DEG C for 50 hours is analyzed by X-ray photoelectron spectroscopy (XPS).
