<P>PROBLEM TO BE SOLVED: To provide a current collector for bipolar secondary battery which is light in weight compared with a metallic foil current collector, and prevents liquid junction between a positive electrode layer and a negative electrode layer in the bipolar electrode. <P>SOLUTION: The current collector 11 includes a structure which is constructed of a layer 3 consisting of a crystalline resin 1a having a melting point of 120°C or more and a conductive material 2. As the crystalline resin 1a, any one kind selected from a high density polyethylene, polypropylene, polystyrene, polyethylene-terephthalate, and polyamide is desirable. <P>COPYRIGHT: (C)2010,JPO&INPIT |
