    Abstract: An electrolytic capacitor includes a capacitor element, a liquid component, a case housing the capacitor element and the liquid component, and a sealing member sealing the case. the capacitor element includes a porous sintered body including a dielectric layer, a cathode foil facing at least a part of the porous sintered body, and a conductive polymer covering at least a part of a surface of the dielectric layer. The conductive polymer is in contact with the cathode foil. And a void in the capacitor element is impregnated with the liquid component.

    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.

    Abstract: An electrolytic capacitor includes an anode body, a cathode body, and a conductive polymer and a liquid component that are disposed between the anode body and the cathode body. The liquid component contains an acid component, a base component, and an aromatic additive. The acid component includes at least one of an aromatic carboxylic acid and an aromatic carboxylic acid derivative. The at least one of the aromatic carboxylic acid and the aromatic carboxylic acid derivative includes at least two carboxy groups and at least one aromatic ring. A content proportion of the base component in the liquid component is more than or equal to 1% by mass. The aromatic additive includes an electron withdrawing group and an electron donating group. A content ratio of the aromatic additive contained in the liquid component is more than or equal to 50 parts by mass with respect to 100 parts by mass of the conductive polymer.
