PROBLEM TO BE SOLVED: To provide a thermoelectric converter high in thermoelectric conversion efficiency by reducing a transmission loss of heat energy. SOLUTION: This thermoelectric converter 1 is equipped with a piping part 5 that is formed in a passage 7, an airtight casing 10 which has a low-temperature side casing 15 arranged around the piping wall 6 of the piping part 5 so as to oppose the piping wall 6 and a casing sidewall 12 that partitions the space between the piping wall 6 and the low-temperature side casing wall 15 and forms a sealed storage space 11 inside, and a thermoelectric conversion module 20 which has a high-temperature side electrode 22 that is arranged inside the storage space 11 of the airtight casing 10 and provided on the side of the piping wall 6 of the piping part 5, a low-temperature side electrode 23 that is provided on the side of the low-temperature-side casing wall 15, and a p-type semiconductor layer 27 and an n-type semiconductor layer 26 that are inserted between the high-temperature-side electrode 22 and the low-temperature-side electrode 23. The low-temperature-side casing wall 15 includes at least a low-temperature-side insulating layer 14, and the storage space 11 of the airtight casing 10 is charged with vacuum or inert gas.
