Abstract:
An electrolytic capacitor includes: an anode body; a dielectric layer; a first conductive polymer layer; a second conductive polymer layer; and a first intermediate layer. The dielectric layer is formed on the anode body. 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 intermediate layer is formed between the first conductive polymer layer and the second conductive polymer layer. The first intermediate layer includes both a cationic agent and an anionic agent, and the first intermediate layer has a first region and a second region, the first region facing the first conductive polymer layer, the second region facing the second conductive polymer layer. The first region contains a greater amount of the anionic agent than the second region, and the second region contains a greater amount of the cationic agent than the first region.
