Beschreibung
Zusammenfassung:	The invention provides an electrode binder for a nonaqueous secondary battery, which can obtain a secondary battery which has an electrode active material layer having few cracks and a high peeling strength to a current collector, and which has a low internal resistance and a good cycle characteristic; and a nonaqueous secondary battery electrode. The electrode binder for a nonaqueous secondary battery contains a resin component and is water-soluble. The surface free energy γB at 23°C is 70 mJ/m2 or less, and the dipole component γpB of the surface free energy is 26 mJ/m2 or less.
