PROBLEM TO BE SOLVED: To provide a bipolar battery made by using a novel collector excellent in corrosion resistance at a positive electrode side and not alloying with lithium at a negative electrode side, with its thickness appropriate in comparison with an electrode layer and an electrolyte layer. SOLUTION: Of the bipolar battery 1 having a structure of laminating electrode lamination bodies formed by laminating a positive electrode layer 5 on one face of a sheet of polymer electrolyte film 3 and a negative electrode layer 7 on the other face through an electron conductive layer, the electron conductive layer 11 contains mainly an insulating polymer and an electron conductive filler.
