To prevent deformation of a negative electrode current collector due to expansion and shrinkage in volume of a negative electrode active material accompanying charge/discharge, or dimensional change of a battery due to expansion of a negative electrode active material in the thickness direction.
In this nonaqueous electrolyte second battery, a fine negative electrode current collector exposed portion, on which lines are provided having a width of not more than 100 μm, or lines having a width of not more than 100 μm and intersected each other is formed on a negative electrode active material layer coated on a negative electrode current collector. The fine negative electrode current collector exposed portion is formed in such a way that a negative-electrode mixture layer containing a negative electrode active material is coated on the exposed portion from above a mesh made of nylon fiber etc., then the mesh is removed, or a negative-electrode mixture layer is coated on the surface of a transfer roll preliminarily having grooves, and then transferred on the negative electrode collector.
