Zusammenfassung:PROBLEM TO BE SOLVED: To provide a binder resin composition for a nonaqueous electrolyte system energy device that is proper in adhesiveness with respect to a collector of an electrode, especially one for an anode, and a swelling preventing properties with respect to electrolyte solution, and with superior in suppleness/flexibility of the electrode, as well as an electrode for a nonaqueous electrolyte system energy device, and a nonaqueous electrolyte system energy device with high capacity and small capacity fall in a charging/discharging cycle with the use of the binder resin composition, especially, anode for a lithium battery and a lithium battery. SOLUTION: The binder resin composition for the nonaqueous electrolyte system energy device electrode, made by containing a nitrile polymer containing 80% by mass or more of repetition units, originated from a nitrile-group-containing monomer, and the nonaqueous electrolyte system energy device electrode, as well as the nonaqueous electrolyte system energy device are provided.
