The electrolytic capacitor of the present invention includes an anode body having a dielectric layer, a solid electrolyte layer in contact with the dielectric layer of the anode body, and an electrolytic solution. The solid electrolyte layer contains a π-conjugated conductive polymer. The electrolytic solution includes a solvent and a solute, and the solvent includes a diol compound and a sulfone compound. The ratio of the diol compound contained in the solvent is 10% by mass or more. The ratio of the sulfone compound contained in the solvent is 30% by mass or more. The total ratio of the diol compound and the sulfone compound contained in the solvent is 70% by mass or more. |
