A multi-stage Stirling engine (1) mounted on a car, wherein displacer pistons (6) and (7) and power pistons (8) and (9) are slidably fitted in series into two cylinders (4) and (5) of the engine, and heated fluid which is exhaust gas from the internal combustion engine mounted on the car flows in series through the cylinders (4) and (5) to heat helium gas as working fluid in the Stirling engine. These two cylinders (4) and (5) are disposed with the orientations thereof aligned with each other, and heaters (16) and (17), regenerative heat exchangers (16) and (17), and coolers (20) and (21) are disposed midway between these cylinders (4) and (5), whereby the flat and compact Stirling engine can be provided.
