PROBLEM TO BE SOLVED: To provide a manufacturing method of nonaqueous electrolytic solution secondary battery capable of maintaining the measurement of the sheathing member of a metallic external can in a prescribed measurement even at charge and discharge. SOLUTION: The manufacturing method of the nonaqueous electrolytic solution secondary battery having a sheathing member 1 in which, an electrode group 6 composed of a cathode 9, an anode 7, and a separator 8, and nonaqueous electrolyte liquid, includes a preparatory charging process carried out in a state that the sheathing member is opened; a process of preserving the battery for 15 to 20 days at a temperature of 10°C or higher and less than 15°C, for 12 to 17 days at a temperature of 15°C or higher and less than 20°C, for 10 to 15 days at a temperature of 20°C or higher and less than 25°C, for 5 to 10 days at a temperature of 25°C or higher and less than 30°C, and for 2 to 5 days at a temperature of 30°C or higher and less than 35°C or for 1 to 2 days at a temperature of 35°C or higher and less than 40°C, after sealing the sheath member, and a process of applying a standard charging after preservation.
