Abstract: The nonaqueous electrolyte secondary battery includes a rolled electrode assembly 14E formed by rolling a positive electrode plate 11 and a negative electrode plate 12 with a separator 13 interposed therebetween, the separator 13 is fixed on the outermost periphery of the rolled electrode assembly 14E with an adhesive tape for fixing a roll end 30e, an exposed portion of a negative electrode substrate 12c without an active material mixture layer 12b is placed on an outermost periphery side of the negative electrode plate 12, a negative electrode tab 12a is connected to the negative electrode substrate 12c on an outermost periphery side, and the adhesive tape 30e is not overlapped with a roll end 11d of the positive electrode plate 11 and a roll end 12d of the negative electrode substrate 12c. Thus the battery is seldom broken even when charging and discharging are repeatedly provided at high voltage.
