As a result, the internal heat storage material 32 for heat generation and the steam generation flow path member 50 undergo a dehydration reaction, and this heat is stored in the heat generation heat storage material 32 and the steam generation flow path member 50. After that, a vacuum pump or the like is connected to the on-off valve 70 to create a vacuum in the internal space, the on-off valve 66 is closed, and then water W is injected into the tank 30 via the on-off valve 70 to close the on-off valve 70.
