Beschreibung
Zusammenfassung:	The present disclosure provides an electrolytic capacitor for middle or high voltage application of 160 V or more, which can suppress the total amount of gas generated inside the electrolytic capacitor. An electrolytic capacitor includes anode foil on which dielectric oxide film is formed, and a cathode body. The cathode body includes cathode foil formed of valve action metal and a carbon layer formed on the cathode foil. The anode foil and the cathode body have capacitance so that when capacitance X of the anode foil per unit area is 1, ratio of capacitance Y of the cathode body per the same unit area is equal to or more than 10.
