SOLUTION: This vapor sterilizer is equipped with a chamber 1 with a heater 4 at the inner bottom for storing a material to be sterilized, a water storage tank 8 for storing water injected into the chamber 1, a water supply and drain pipe 6 connecting the water storage tank 8 to the chamber 1, a water supply and drain valve 7 for operating the water supply and drain pipe 6, an exhaust pipe 9 for exhausting a vapor generated in the chamber 1 and an exhaust valve 10 for operating the exhaust pipe 9. In addition, cooling means 13, 14 are installed at the water supply and drain pipe 6 and the exhaust pipe 9 respectively. Thus it is possible to keep a high temperature fluid cooled to some degree, and therefore, mitigate a thermal stress to be inflicted to the water supply and drain valve 7 and the exhaust valve 1.0 by a passing high temperature fluid.
