PROBLEM TO BE SOLVED: To provide a power storage device with increased voltage resistance by using a conductive separator and a manufacturing method thereof.SOLUTION: The power storage device includes a power storage element and electrolyte. The power storage element is constituted of an anode body, a cathode body opposing to the anode body and a separator disposed between the anode body and the cathode body. The separator includes a separator base material and an electroconductive polymer coated on the separator base material. The electrolyte is impregnated in the power storage element. The separator base material has a first plane opposing to the anode body and a second plane opposing to the cathode body. The deposition amount of the electroconductive polymer coated on the first plane of the separator base material is smaller than the deposition amount of the electroconductive polymer coated on the second plane. |
