PROBLEM TO BE SOLVED: To provide a manufacturing method of a nonaqueous electrolytic solution battery in which the nonaqueous electrolytic solution is supplied effectively in a short time in the manufacturing method of the battery in which electrolytic solution is supplied after the group of electrode plates in a state that a positive electrode plate and a negative electrode plate are insulated via a separator is housed in a battery can, and a nonaqueous electrolytic solution battery superior in charging and discharging cycle characteristics. SOLUTION: In the state that the battery can in which the group of electrode plates is housed and the electrolytic solution are warmed, the cycles of normal pressure state and reduced pressure state are repeated at least twice, and the electrolytic solution is supplied separately. As for the reduced pressure state, it is preferable not to exceed the pressure value of the previous reduced pressure state for each cycle, and the pressure of the reduced pressure state is preferably between 40 kPa and 80 kPa, and the warming temperature is preferably between 40°C and 100°C.
