    • A current collector for a battery comprising: (1) a layer (1) formed from an electrically conductive material including a polymer material 1 including at least one compound selected from the group consisting of following (a) to (d), and electrically conductive particles 1, (a) a polymer compound having an alicyclic structure, (b) a saturated hydrocarbon polymer compound having a hydroxyl group, (c) a phenoxy resin and an epoxy resin, and (d) an amine having an amine equivalent of 120 g/eq or less and an epoxy resin (provided that, a blending ratio of the epoxy resin and the amine is 1.0 or more in terms of a ratio of the number of active hydrogen atoms in the amine to the number of functional groups in the epoxy resin); (2) a layer (2) which is formed on at least one surface of the layer (1), and which is a metal thin film layer or the layer (2) formed from an electrically conductive material including a polymer material 2 and an electrically conductive carbon particles 2; and (3) a layer (3) formed from an electrically conductive material including a polymer material 3 and electrically conductive particles has a stability to an equilibrium potential environment in a negative electrode, a low electric resistance, a blocking property to a solvent in an electrolytic solution, and a blocking property to a component in an electrolyte. In addition, the current collector for a battery has a high capacity retention rate, and thus a battery durability is improved. When the current collector is used, it is possible to obtain a battery which realizes both of weight reduction and long-term reliability.
