An electrolytic capacitor includes a capacitor element, a liquid component, an outer case, and a sealing body. The capacitor element includes an anode body having a dielectric layer, and a solid electrolyte layer in contact with the dielectric layer. The liquid component is in contact with the solid electrolyte layer. The outer case houses the capacitor element and the liquid component. The sealing body seals an opening of the outer case. The liquid component contains a first component, which is an aliphatic polyol compound having two or more hydroxy groups per molecule. The aliphatic polyol compound includes at least one of a compound having a C3 carbon chain in a main chain and a compound having no C3 carbon chain but having one to four ether oxygen atoms in a main chain. The sealing body includes a polymer having no double bond in a main chain.
