PROBLEM TO BE SOLVED: To suppress the self discharge after cell shipment.SOLUTION: In a method for injecting a nonaqueous electrolytic solution, a nonaqueous electrolytic solution is injected into a battery case from a liquid-pouring spout formed in a first side wall of the battery case. The nonaqueous electrolytic solution injected into the battery case flows along an inner face of the battery case according to the gravity in a state in which the battery case is held so that a part of a negative electrode internal terminal extending from the upside of a negative electrode of an electrode body housed in the battery case to the first side wall, where the negative electrode internal terminal is fixed to the first side wall is located below the liquid-pouring spout in a gravity direction.SELECTED DRAWING: Figure 1 |
