Abstract
An electrolytic capacitor has a capacitor element formed from an anode foil, a cathode foil opposed to the anode foil and a release paper sandwiched between the anode foil and the cathode foil, and an electrolytic solution, the content of cation(s) in said release paper being not more than 500 ppm. The electrolytic capacitor has a low impedance, excellent low-temperature stability and heat resistance, and good working life characterstics.
