Abstract
An electrolytic capacitor according to the present invention includes a wound element formed by winding an anode body consisting of a band-shaped metal foil and a dielectric coat provided on the surface of the metal foil and a cathode body consisting of a band-shaped metal foil in the longitudinal direction. The electrolytic capacitor includes a first conductive polymer layer provided on the surface of the anode body. The first conductive polymer layer is provided to be more thickly present on an end portion of the anode body in the width direction than on a central portion of the anode body in the width direction on the surface of the anode body.
