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. The acid component contains a first aromatic compound having a hydroxyl group. A proportion of the first aromatic compound in the acid component ranges from 30% by mass to 100% by mass, inclusive.
