Abstract: A power storage device includes a positive electrode and a negative electrode disposed opposite to the positive electrode. The positive electrode and the negative electrode are respectively disposed on at least one surface of a current collector foil. The positive electrode and the negative electrode respectively include an active material, a conductive auxiliary and an adhesive, wherein the active material includes a porous material, an oxidation-reduction electrode material, or combination thereof. At least one of the positive electrode and the negative electrode has a multilayer structure containing three or more layers. The concentration of the oxidation-reduction electrode material in the outmost layer of the multilayer structure is the lowest.
