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 electrolytic solution. The electrolytic solution contains a solvent and a solute. The solvent contains a glycol compound. The solute contains an acid component and a base component. A mass of the acid component in the solute is greater than a mass of the base component in the solute. The acid component contains a first aromatic compound having a hydroxyl group.
