In a nonaqueous electrolyte secondary battery using an electrode in which a mixture layer is formed on a current collector using an aqueous slurry, a nonaqueous electrolyte secondary battery that can be produced efficiently, has high adhesion strength in an electrode, and can improve battery performance. Get It is a nonaqueous electrolyte secondary battery which has a positive electrode, a negative electrode, and a nonaqueous electrolyte, The electrode of at least one of a positive electrode and a negative electrode forms the precoat layer 6 which consists of a latex type binder and an aqueous dispersing agent on the electrical power collector 1, And an electrode obtained by applying an aqueous slurry containing an active material, a latex binder and an aqueous dispersant on the precoat layer 6 to form a mixture layer 2, and then drying. |
