Abstract:
A disclosed electrolytic capacitor includes a capacitor element. The capacitor element includes an anode body, a dielectric layer formed on a surface of the anode body, a cathode body, and a electrolyte layer and a separator that are disposed between the dielectric layer and the cathode body. The electrolyte layer includes a non-aqueous solvent, conductive particles, and a conductive polymer. An amount of the conductive particles present in a first portion included in the electrolyte layer and located on the dielectric layer side is different from an amount of the conductive particles in a second portion included in the electrolyte layer and located on the cathode body side.
