A conductive film, a conductive film of the current collector, the bipolar battery and a battery

The present invention provides a polymer material containing a conductive particles and the conductive film 1 of a conductive material layer 1 is formed, a negative electrode which is excellent in stability with respect to the equilibrium potential of the environment, and the thickness direction of the resistance per unit area than low, if to be used as the multilayer conductive film, the interlayer adhesion is more excellent, if used as a current collector, both weight reduction and durability can be obtained a battery, wherein the polymeric material comprises 1 any material (1) to (4) below, (1) an amine and an epoxy resin (wherein, with an epoxy resin and an amine number of active amine hydrogen ratio with respect to the ratio of the number of epoxy functional groups It is 1.0 or more), (2) an epoxy resin and a phenoxy resin, (3) a saturated hydrocarbon polymer having a hydroxyl group, (4) a curable resin and an elastomer.
