An external combustion engine is disclosed, comprising a container ( 11 ) for sealing a working liquid ( 12 ) in a way adapted to allow the liquid to flow therein, a heater ( 13 ) for heating and vaporizing the working liquid ( 12 ) in the container ( 11 ), and a cooler ( 14 ) for cooling and liquefying the vapor of the working liquid ( 12 ) heated and vaporized by the heater ( 13 ). The displacement of the working liquid ( 12 ) caused by the volume change of the vapor of the working liquid ( 12 ) is output by being converted into mechanical energy. In the heated portion ( 11 d) of the container ( 11 ) for vaporizing the working liquid ( 12 ), the direction of displacement of the working liquid ( 12 ) at the parts ( 17, 19 ) far from the cooler ( 14 ) is changed with respect to the direction of displacement at the part ( 16 ) near to the cooler ( 14 ).
