Abstract:
An electrolytic capacitor includes an anode body having a dielectric layer; a solid electrolyte layer in contact with the dielectric layer of the anode body; and an electrolyte solution. The solid electrolyte layer includes a π-conjugated conductive polymer. The electrolyte solution contains a solvent and a solute, and the solvent contains a glycol compound and a sulfone compound. A proportion of the glycol compound contained in the solvent is 10% by mass or more. A proportion of the sulfone compound contained in the solvent is 30% by mass or more. A total proportion of the glycol compound and the sulfone compound contained in the solvent is 70% by mass or more.
