Abstract:
An electrolytic capacitor includes a capacitor element and a liquid component, wherein the capacitor element includes an anode body having a dielectric layer on a surface thereof, and a conductive polymer compound covering at least a portion of the dielectric layer. The liquid component includes an acid component, a base component, a solvent, and an antioxidant. The solvent includes water and a polyol compound. The acid component includes a coordination compound including a central atom, and an organic molecule having a plurality of coordination atoms bonded to the central atom, and at least one of the plurality of coordination atoms is an oxygen atom bonded to a carbonyl group.
