Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a reliable electrolytic capacitor having heat-resistance characteristics (for example, dimension stability by heating). SOLUTION: In the electrolytic capacitor for impregnating and keeping an electrolytic solution by interposing a separator between positive electrode foil and negative electrode foil, a separator is used, wherein the separator has a nonwoven cloth including a synthetic fiber made of polyketone fiber comprising an alternating copolymer of carbon monoxide and olefin having a small water content, high chemical resistance, and a repeating unit of ≥90%, thus extending the life of an electrolyte in the high temperature electrolytic solution.
