  "textContent": "Provided is a technique for preventing plastic deformation of a battery case due to restraint during initial charging. A manufacturing method disclosed herein is a manufacturing method of a non-aqueous electrolyte solution secondary battery. This method includes assembling to construct a secondary battery assembly, and initial charging of the secondary battery assembly. In the initial charging, the initial charging is started with the secondary battery assembly restrained or not restrained; when a negative electrode potential of the secondary battery assembly reaches 0.6 V, a restraint force P1 is applied to the secondary battery assembly, wherein the restraint force P1 is greater than a restraint force applied before the negative electrode potential reaches 0.6 V; and the restraint force P1 is applied to the secondary battery assembly until the negative electrode potential reaches at least 0.3 V.",
