An electrolytic capacitor element that includes: an anode having a front end face and a base end face; a dielectric layer on at least one main face of the anode but excluding the base end face; a mask layer on the dielectric layer adjacent the base end face; and a cathode on the dielectric layer on the front end face side from the mask layer, wherein the cathode includes a solid electrolyte layer and a conductive layer, the solid electrolyte layer includes a first layer including a first conductive polymer doped with a first dopant and a second layer including a second conductive polymer doped with a second dopant, the second layer is partially disposed in the plane of the solid electrolyte layer, and the second conductive polymer is more likely to be dedoped than the first conductive polymer
