A method for producing a negative electrode for a nonaqueous electrolyte secondary battery, and a nonaqueous electrolyte secondary battery obtained therewith are disclosed. The negative electrode includes a negative electrode current collector, a negative electrode active material layer provided on the surface of the negative electrode current collector, and a first film which has lithium ion permeability and which coats at least a portion of the surface of the negative electrode active material layer and partially coats the surface of the negative electrode current collector. The first film preferably contains a first lithium compound containing an element M, an element A, and lithium. Herein, Mis at least one selected from the group consisting of P, Si, B, V, Nb, W, Ti, Zr, Al, Ba, La, and Ta; and Ais at least one selected from the group consisting of F, S, O, N, and Br.
