An electrolytic capacitor includes a capacitor element and electrolytic solution. The capacitor element includes an anode body with an oxide film, and a solid electrolyte contacting the oxide film. The electrolytic solution contains a solvent and a solute. The solvent contains at least one selected from the group consisting of a lactone compound, a glycol compound, and a sulfone compound. The solute includes a first acid component and a base component. The first acid component includes at least one of a benzenedicarboxylic acid and a derivative of the benzenedicarboxylic acid. The base component includes at least one of an amine and an amidine. A concentration of the solute in the electrolytic solution ranges from 15% by mass to 40% by mass, inclusive. A ratio (V/Vw) of a formation voltage V of the oxide film to a rated voltage Vw of the electrolytic capacitor is less than or equal to 1.7.
