Abstract:
An electrolytic capacitor includes an anode body, a dielectric layer disposed on a surface of the anode body, a solid electrolyte layer that is in contact with the dielectric layer, and an ion conductor that is liquid at room temperature. The solid electrolyte layer includes a conductive polymer. The ion conductor includes a solvent, an acid component, and a base component. The content proportion of the solvent in the ion conductor is more than 10% by mass and less than or equal to 60% by mass. The total content proportion of the acid component and the base component in the ion conductor is more than or equal to 40% by mass and less than 90% by mass. A melting point of the ion conductor is lower than or equal to −10° C.
