Abstract
An electrolytic capacitor includes an anode body, a dielectric layer disposed on a surface of the anode body, and a solid electrolyte layer disposed on a surface of the dielectric layer. The solid electrolyte layer includes a conductive polymer and a first compound. The first compound has a naphthalene skeleton, and includes at least one COOM1 group and at least one sulfonate group. The at least one sulfonate group is bonded to the naphthalene skeleton. The at least one COOM1 group is bonded to the naphthalene skeleton, where M1 is a hydrogen atom, a metal atom, or an onium group.
