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
