Abstract: A disclosed manufacturing method includes a laminated body formation step of forming a laminated body by laminating an anode foil, a cathode foil, and a separator such that the separator is arranged between the anode foil and the cathode foil, and a polymer layer formation step of impregnating the laminated body with a dispersion liquid containing a conductive polymer and a dispersion medium, and then evaporating at least a portion of the dispersion medium of the dispersion liquid in the laminated body to form a conductive polymer layer containing the conductive polymer in the laminated body. The laminated body formation step further includes a step of surrounding an outer periphery of the laminated body with a binding member. The separator has a protrusion part that protrudes from the binding member. In the polymer layer formation step, the laminated body is impregnated with the dispersion liquid from the protrusion part.
