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.
