Abstract: An electrolytic capacitor includes an anode body, a dielectric layer covering the anode body, a first solid electrolyte layer covering the dielectric layer, and a second solid electrolyte layer covering the first solid electrolyte layer. The first solid electrolyte layer contains a first conductive polymer including polythiophene as a basic skeleton. The second solid electrolyte layer contains a second conductive polymer including polypyrrole as a basic skeleton. A conductivity of the first solid electrolyte layer is less than or equal to 2 S/cm.
