Beschreibung
Zusammenfassung:	Provide is an electrolytic capacitor for a middle-to-high voltage application that is equal to or higher than 100 V which suppresses the total amount of gas to be produced in the electrolytic capacitor. The anode foil of the electrolytic capacitor includes an enlarged surface portion provided with tunnel-shape pits formed from the foil surface in the thickness direction of the foil, and a dielectric oxide film formed on the surface of the enlarged surface portion. The cathode body of the electrolytic capacitor includes a cathode foil formed of a valve acting metal, and a carbon layer formed on the cathode foil.
