Abstract
An electrolytic capacitor includes: an anode body having a dielectric layer; a solid electrolyte layer in contact with the dielectric layer; and an electrolytic solution. The electrolytic solution contains a solvent and a solute. The solvent contains a glycol compound. The solute contains a carboxylic acid component and a base component. A ratio of the carboxylic acid component in the solute is 200 parts by mass or more with respect to 100 parts by mass of the base component.
