Abstract: A tubular heat exchanger, with a thermoelectric power generation function, includes: a thermoelectric power generation module 2 mounted on an outer circumferential surface of the heat exhaust tube 1; and a cooling pipe 3 mounted on an outer circumferential surface of the thermoelectric power generation module 2. The cooling pipe 3 is for allowing a cooling material to flow therethrough.

The cooling pipe 3 is in tight attachment to the outer circumferential surface of the thermoelectric power generation module 2.
