To prevent the internal pressure of a container from exceeding the saturated steam pressure of a fluid during operation and the fluid vaporized by heating from being liquefied in a steam engine.
In this steam engine, a heater 12 and a cooler 13 are installed in a fluid container 11 sealed with a working fluid 20, the working fluid is vaporized by heating by the heater 12, and the vaporized working fluid is cooled by the cooler 13 for liquefication to generate a cyclic pressure fluctuation in the fluid container 11 so as to reciprocatingly move a piston by the pressure fluctuation. A cylindrical pressure regulating part 30 capable of regulating the volume of the fluid container by a regulator screw 32 is formed in the fluid container 11. In manufacturing the engine, after the working fluid 20 is sealed in the fluid container 11, the volume of the fluid container 11 is increased by utilizing the pressure regulating part 30. As a result, since the pressure of the fluid container 11 is lowered, it can be suppressed that the internal pressure exceeds a saturated steam pressure during the operation of the engine.
