摘要

An electrolytic capacitor includes an anode body with a dielectric layer; a solid electrolyte layer in contact with the dielectric layer; and an electrolytic solution. The solid electrolyte layer includes a π-conjugated conductive polymer and a first sulfonic acid. The electrolytic solution includes a solvent and an acid component. The solvent includes a glycol compound. And a proportion of the glycol compound in the solvent is equal to or more than 50% by mass.
