    摘要： In a wound electrode group, a positive electrode includes positive electrode active material layers formed on both surfaces of a band-like positive electrode current collector, and a negative electrode includes negative electrode active material layers on both surfaces of a band-like negative electrode current collector. Charge capacity of the negative electrode falls within a range of 83-99% of theoretical capacity of the negative electrode in a full charge state of a nonaqueous electrolyte secondary battery. An active material mass M1 per unit area of a negative electrode active material layer formed on an outer circumference of the negative electrode current collector, and an active material mass M2 per unit area of a negative electrode active material layer formed on an inner circumference satisfy a relational expression of M1/M2
