An energy storage device before pre-doping includes positive electrodes, negative electrodes, separators, a cover, an electrolyte solution, a positive terminal, a negative terminal, and pre-doping metal foil. Each of the positive electrodes and the negative electrodes respectively include: positive collector foil and negative collector foil each having holes; and a positive active-material layer and a negative active-material layer arranged on at least one side of the collector foil. Either one or both of the positive electrodes and the negative electrodes include a pre-doping-targeted electrode, in which the pre-doping metal foil is arranged in direct contact with the surface of the active-material layer, and a non-arrangement part, in which the pre-doping metal foil is not arranged, is formed in at least part of the outer periphery of the active-material layer.
