To provide a thermoelectric generation system capable of efficiently generating power by inhibiting heat from residing near a heat dissipation fin so as to ensure the temperature difference in a thermoelectric conversion module thermoelectric conversion module.SOLUTION: In the thermoelectric conversion module, thermoelectric conversion modules having a plurality of thermoelectric elements 14 mounted on flexible substrates 12, 16 are attached to a heat discharge pipe 10. In the thermoelectric conversion modules, a first thermoelectric conversion module 11 and a second thermoelectric conversion module 21 are layered, the first thermoelectric conversion module 11 is attached to the heat discharge pipe 10, and a plurality of heat dissipation fins 31 are attached to the second thermoelectric conversion module 21.SELECTED DRAWING: Figure 1
