Abstract: Disclosed is an electrolytic capacitor including a capacitor element. The capacitor element includes an anode body having a dielectric layer formed at a surface of the anode body, and an electrolyte layer disposed adjacent to the dielectric layer. The electrolyte layer contains a conductive polymer doped with a dopant, conductive particles, and a non-aqueous solvent.

Abstract: An electrolytic capacitor includes a capacitor element. The capacitor element includes an anode body and an electrolyte layer. The anode body has a dielectric layer on a surface of the anode body. The electrolyte layer is disposed to be adjacent to the dielectric layer. The electrolyte layer contains a first conductive polymer and a non-aqueous solvent. The first conductive polymer is a self-doped conductive polymer.
