PROBLEM TO BE SOLVED: To improve output in an external combustion engine having a plurality of heating parts formed therein. SOLUTION: The external combustion engine is provided with a vessel 11 in which working medium 12 is filled under a liquid condition in such a manner that the same can flow, has a heating part 17 heating part of the working medium 12 and forming vapor of the working medium 12 and a cooling part 19 cooling and liquefying the vapor formed in the vessel 11, makes working medium volumetrically fluctuate by formation of vapor and liquefaction, and outputs mechanical energy after converting displacement of liquid portion of the working medium 12 generated by volumetric fluctuation of the working medium 12 to the mechanical energy. At least a section communicating with the heating part 17 in the vessel 11 branches to a plurality of tubular parts 11c. The plurality of heating parts 17 are formed to communicates with the plurality of tubular parts 11c respectively. A plurality of vapor reservoir 22 keeping vapor of the working medium 12 are formed to communicate with the plurality of heating parts 17 respectively. The plurality of vapor reservoir 22 mutually communicate with one another. COPYRIGHT: (C)2008,JPO&INPIT
