Abstract:
An electrolytic capacitor includes an anode body, a dielectric layer disposed on the anode body, a solid electrolyte layer disposed on the dielectric layer, and a cathode lead-out layer disposed on the solid electrolyte layer. The solid electrolyte layer contains a first conductive polymer having a thiophene skeleton and a second conductive polymer having an aniline skeleton. In the solid electrolyte layer, a mass ratio of the second conductive polymer with respect to a total mass of the first conductive polymer and the second conductive polymer in a region close to the dielectric layer is greater than a mass ratio of the second conductive polymer with respect to a total mass of the first conductive polymer and the second conductive polymer in a region close to the cathode lead-out layer.
