Beschreibung
Zusammenfassung:	An electrolytic capacitor that can suppress a decrease over time of capacity, a cathode body included in the electrolytic capacitor, and a production method of the electrolytic capacitor are provided. The electrolytic capacitor includes an anode foil, a cathode body, and electrolytic solution. The anode foil is formed of valve metal and has dielectric oxide film formed on a surface of the foil. The cathode body includes cathode foil formed of valve metal and a carbon layer laminated on the cathode foil. An interfacial resistance between the cathode foil and the carbon layer is 1.8 mΩ·cm2 or less.
