Abstract
An electrolytic capacitor includes an anode body having a dielectric layer, 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 and a first polymer dopant having a sulfonate group. The second conductive polymer layer includes a second conductive polymer and a second polymer dopant having a sulfonate group. A polymerization degree of the first conductive polymer is lower than a polymerization degree of the second conductive polymer.
