    • This liquid injection device (2) is provided with a nozzle (9) which performs evacuation and liquid injection. The nozzle (9) is provided with: a cylindrical outer circumferential-side nozzle part (15); a cylindrical inner circumferential-side nozzle part (16) which expands and contracts through the outer circumferential-side nozzle part (15); and a columnar shaft part (17) which expands and contracts through the inner circumferential-side nozzle part (16). The outer circumferential-side nozzle part (15) has an electrolyte passage (19) which is disposed between the outer circumferential-side nozzle part (15) and the inner circumferential-side nozzle part (16) and through which an electrolyte flows. The inner circumferential-side nozzle part (16) has a decompression passage (28) which is disposed between the inner circumferential-side nozzle part (16) and the shaft part (17) and through which a gas inside a film outer package (4) is evacuated. The shaft part (17) is provided with a valve (25) which closes a suction hole (29) of the inner circumferential-side nozzle part (16). During the evacuation, the suction hole (29) of the inner circumferential-side nozzle part (16) in the extension state opens at a position that protrudes from a liquid injection port (20) of the outer circumferential-side nozzle part (15) in an axial direction of the outer circumferential-side nozzle part (15).
