PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery in which poor welding of an injection hole and a sealing member, and electrolyte leakage are reduced.SOLUTION: A nonaqueous electrolyte battery includes a metallic exterior member 1, an electrode group 2, a nonaqueous electrolyte, an injection hole 1c, an insulating film 21, and a sealing member 23. The electrode group 2 includes a positive electrode 3 and a negative electrode 4, and is housed in the exterior member 1. The electrode group 2 is impregnated with the nonaqueous electrolyte. The injection hole 1c is open to the exterior member 1. The insulating film 21 covers the periphery of the injection hole 1c at least partially. The sealing member 23 closes the injection hole 1c and is welded to the periphery thereof. |
