Abstract: A method for manufacturing an electrolytic capacitor includes: preparing an anode body that includes a dielectric layer, and forming a solid electrolyte layer on the dielectric layer. The forming of the solid electrolyte layer includes: forming a first conductive polymer layer on the dielectric layer, applying a first treatment liquid to the first conductive polymer layer, and forming a second conductive polymer layer after the applying of the first treatment liquid. The first conductive polymer layer includes a first conductive polymer. The first treatment liquid contains a first compound and a solvent. The first compound has a skeleton of naphthalene or anthraquinone, and includes at least one SO3-containing group bonded to the skeleton. The at least one SO3-containing group is at least one selected from a group consisting of a sulfonic acid group and a sulfonate group.

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.
