Abstract
An electrolytic capacitor includes a capacitor element. The capacitor element includes an anode body having a dielectric layer at a surface of the anode body, and an electrolyte covering part of the dielectric layer. The electrolyte contains a conjugated polymer, a polymer dopant having an anionic group, and a metal ion. The amount of the metal ion is less than 1 equivalent, relative to 1 equivalent of the anionic group.
