PROBLEM TO BE SOLVED: To provide a Stirling engine capable of improving the heat transmission efficiency between a heat absorption part and the outside without deteriorating the performance, and a heat exchange system with the Stirling engine. SOLUTION: This heat exchange system comprises the Stirling engine, and a heat transport means. The Stirling engine comprises a casing 2, a cylinder 3 assembled in the casing 2, a piston 4 reciprocating within the cylinder 3, a linear motor 14 for reciprocating the piston 4 within the cylinder 3, a working space including a compression space 7a for compressing a working medium and an expansion space 7b for expanding the working medium, a radiation part 8 for releasing the heat in the compression space 7a to the outside, a heat absorption part 9 provided in the vicinity of the expansion space 7b to absorb the heat from the outside, a heat transfer member 10 set on the outer surface of the heat absorption part 9, and a refrigerant pipe 11 set on the surface of the heat transfer member 10 to circulate the refrigerant.
