    Abstract: An electrolytic capacitor includes an anode body, a dielectric layer formed on the anode body, a first conductive polymer layer covering at least a part of the dielectric layer, and a second conductive polymer layer covering at least a part of the first conductive polymer layer. The first conductive polymer layer includes a first conductive polymer. The second conductive polymer layer includes a second conductive polymer. The first conductive polymer layer and the second conductive polymer layer each further include a first polymer dopant having a sulfonation degree of S1. At least one of the first conductive polymer layer and the second conductive polymer layer further includes a second polymer dopant having a sulfonation degree of S2. The sulfonation degree of S1 and the sulfonation degree of S2 satisfy a relation of S1

    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 first conductive polymer layer, and a second conductive polymer layer. The anode body includes a dielectric layer. The first conductive polymer layer covers at least a part of the dielectric layer. The second conductive polymer layer covers at least a part of the first conductive polymer layer. The first conductive polymer layer includes a first conductive polymer. The second conductive polymer layer includes a second conductive polymer. At least one of the first conductive polymer layer and the second conductive polymer layer further includes a hydroxy compound. The hydroxy compound has two or more alcoholic hydroxy groups or two or more phenolic hydroxy groups, and has a melting point ranging from 40° C. to 150° C., inclusive.
