PROBLEM TO BE SOLVED: To provide a technology which reduces waste of a laminate sheet member and thereby reduces the manufacturing costs, for example, when a laminate sheet is used for a battery outer container of a battery as typified by a lithium ion battery.SOLUTION: A battery includes an electrode laminate or an electrode wound body, an electrolytic solution, and a laminate sheet serving as a battery outer container. A manufacturing method of the battery includes: a step (b) where a passage of the electrolytic solution is formed around the laminate sheet sandwiching the electrode laminate or the electrode wound body; a step (c) where the electrolytic solution is poured through the passage formed around the laminate sheet; and a step where the passage formed around the laminate sheet is sealed after the electrolytic solution is completely poured. |
