PURPOSE: To provide a manufacturing method of a battery that can improve the yield of manufacture. CONSTITUTION: In a battery that uses an acid solution as an electrolyte and uses a conductive rubber 5 as an outer package, the positive electrode 1 and the negative electrode 2 laminated through a separator 3 are sealed by a gasket 4 fitted with a stainless needle 6 and the conductive rubber 5, and adhered by vulcanization. After vulcanization adhesion, the stainless needle 6 is pulled out and a hole is made. An electrolyte is injected from this hole and the hole is sealed. Since the hole for injecting the electrolyte is formed beforehand, it enables to manufacture the battery with a high yield. |
