PROBLEM TO BE SOLVED: To improve adhesion between an electrode mixture layer and a conductor and electric characteristics. SOLUTION: An electrode for nonaqueous electrolyte secondary battery, an electrode mixture layer containing a binder is formed on a collector (copper foil) 1 in such a manner that binder concentration in the electrode mixture layer is increased near the collector (copper foil) 1. For the purpose, paste different in binder concentration is separately layered two times. Additionally, the binder concentration on the surface of the electrode mixture layer can be increased to prevent the falling of electrode material from the surface. |
