    Abstract: PROBLEM TO BE SOLVED: To provide a binder for an energy device electrode, which can provide satisfactory press workability without causing peeling or breakage in press working, and can form an electrode layer having high adhesion to a current collector, and to provide a method for producing the same. SOLUTION: The binder for energy device electrode includes a latex obtained by multiple-stage emulsion polymerization. The polymer component by emulsion polymerization in the first stage is obtained from a monomer mixture containing an aromatic vinyl compound, a conjugated diene compound, a (meth)acrylate, and a vinyl cyanide compound, and the polymer component by emulsion polymerization in the other stage is obtained from a monomer mixture containing an aromatic vinyl compound, a conjugated diene compound and a (meth)acrylate.
