PROBLEM TO BE SOLVED: To provide a manufacturing method of a battery capable of efficiently manufacturing a highly reliable battery by preventing an electrode group from being generated causing a short circuit due to swelling of electrode plates after charging and discharging. SOLUTION: With a short-circuit inspection method of the battery made by inserting into a battery case the electrode group structured by laminating positive electrode plates 2 and negative electrode plates 3 with separators in between, the positive electrode plates 2 and the negative electrode plates 3 are laminated with the separators 4 in between to comprise the electrode plate group, of which, good ones passing a short-circuit inspection through pressurization are inserted and put in position in the battery case, and an opening part of the case is to be tightly sealed after an electrolyte solution is poured into the case.
