Abstract
An electrolytic capacitor includes wound body, a solid electrolyte layer, and resin layer. Wound body is formed by winding a positive electrode member having a surface with a dielectric film thereon and a negative electrode member. The solid electrolyte layer is formed by impregnating wound body with a dispersion of a conductive polymer or a solution of a conductive polymer, and then drying the dispersion or the solution with which wound body is impregnated. Resin layer covers at least a part of an outer peripheral surface of wound body.
