PROBLEM TO BE SOLVED: To provide a method for manufacturing a laminated battery with high mechanical strength in a heat-seal part, and having enhanced reliability. SOLUTION: The method for manufacturing the laminated battery having an electrode body, including a sheet-like positive electrode, a sheet-like negative electrode, and a separator, and an electrolyte in a laminated film outer packaging of a polygon, as viewed from above, in which the periphery other than one side from which the electrolyte is poured is sealed includes a process of pouring the electrolyte from the one side into the inside of the laminated film outer packaging housing the electrode body; and a process sealing the laminate film outer packaging by heat-sealing the one side used for pouring the electrolyte in the periphery of the laminated film outer packaging from the battery inside toward the battery outside, as viewed from the above, in a state with the pressure of the inside of the laminated film outer packaging is reduced.
