A nonaqueous electrolyte secondary battery includes an electrode group in which a positive electrode plate including a positive electrode active material formed on a positive electrode current collector and a negative electrode plate including a negative electrode active material formed on a negative electrode current collector are wound with a separator interposed therebetween, and a tensile elongation rate of the positive electrode plate is larger than a tensile elongation rate of the negative electrode plate. |
