An electrolytic capacitor includes a capacitor element and a liquid. The capacitor element includes an anode foil, a cathode foil disposed to face the anode foil, and a conductive polymer layer that is disposed between the anode foil and the cathode foil. A first layer including at least one selected from the group consisting of carbon, nickel, a nickel compound, titanium, and a titanium compound is disposed on the cathode foil. The conductive polymer layer includes a conductive polymer. A proportion of water in the liquid ranges from 0.1% by mass to 6.0% by mass, inclusive. |
