Abstract
A method for producing cell 1, which includes cell element 4 wherein positive electrode plate 41 and negative electrode plate 42 are laminated with an interposal of separator 43 therebetween; and outer case 5 which houses cell element 4 together with an electrolyte solution. An electrolyte solution injection step for forming cell 1 by having outer case 5 contain cell element 4 and electrolyte solution (step S1), a charging step for charging cell 1 (step S2), and an impregnation condition inspection step for inspecting an impregnation condition of the electrolyte solution into cell element 4 after charging cell 1 are conducted in the order of the electrolyte solution injection step, the charging step and the impregnation condition inspection step.
