To provide a nonaqueous electrolytic solution secondary battery wherein temperature-rise of the battery is less even if a large current flows by occurrence of an exterior short circuit, further wherein insertion insufficiency of winding electrode body is difficult to occur in the manufacturing process, and wherein the productivity is high.
In the nonaqueous electrolytic solution secondary battery comprised that nickel negative electrode reed 12 used in a current collection of the negative electrode wherein active substances are coated on both faces of belt-shaped copper foil and molded is welded to the battery can 5, the ratio of the battery capacity and the cross sectional area of the negative electrode reed 12 is made to be from 1.6 Ah/mm
