A heat engine includes a container in which a liquid piston made of a liquid operation fluid is sealed to flow therein, an exterior evaporator located outside of the container to generate vapor of the operation fluid, a suction portion arranged at one end side of the container to draw the vapor generated in the exterior evaporator into the container, an expansion portion in which the vapor drawn into the container is expanded to cause a displacement of the liquid piston, an output portion arranged at the other end side of the container to convert the displacement of the liquid piston to a mechanical energy, a liquid piston discharge portion for discharging a part of the liquid operation fluid as the liquid piston from the container, and a vapor discharge portion configured to discharge the vapor without being condensed in the container to outside of the container.
