PROBLEM TO BE SOLVED: To provide a method of manufacturing a battery which allows for enhancement of production efficiency, because electrolyte does not overflow from the aperture of a film armor material.SOLUTION: A method of manufacturing a battery includes a housing step for housing an electrode laminate 60, laminating a plurality of sheet-like positive electrodes and a plurality of sheet-like negative electrodes via a separator therebetween, in a film armor material 90 having an aperture 93, an opening step for widening the opening space (S) of the aperture by applying a stress to the film armor material 90, a liquid injection step for injecting electrolyte from the aperture 93 in a state where the opening space (S) of the aperture 93 is widened by the opening step, and an impregnation step for performing vacuum impregnation in a state where the opening space (S) of the aperture 93 is widened by the opening step, following to the liquid injection step. |
