    Abstract: A manufacturing method according to the present invention is a method for manufacturing a nonaqueous electrolyte secondary battery including graphite as a negative-electrode active material. The manufacturing method includes: a step of assembling the battery including a positive electrode and a negative electrode; and a step of performing an initial charging process of performing first charging on the battery. In the initial charging process, charging is performed at a relatively large first current value when a gas generation amount caused in the battery during the charging does not depend on a charging current value, and the charging is performed at a second current value smaller than the first current value when the gas generation amount depends on the charging current value.
