    摘要： A negative electrode for a non-aqueous electrolyte secondary battery including a current collector, and an electrode material layer including an electrode material capable of reversibly absorbing and desorbing Li ions is provided. The electrode material includes at least one element selected from the group consisting of Si, Sn and Al; the surface of the current collector is provided with protrusions; the electrode material layer is disposed on the surfaces of the current collector and the protrusions; and the protrusion has a portion facing the surface of the current collector other than a portion that is brought into contact with the current collector. Thus, a negative electrode for a non-aqueous electrolyte battery having high properties such as an energy density, charging/discharging cycle property, and the like, and a non-aqueous electrolyte secondary battery can be provided.
