Abstract
A thermoelectric conversion device that eliminates differences in the distance between two adjacent junctions. The thermoelectric conversion device includes an insulative core. A thermocouple assembly is formed spirally around the insulative core contacting the circumferential surface and includes a plurality of series-connected thermocouples. Each of the thermocouples defines a single loop of the spiral and has a first metal body, which is formed in half of the loop, and a second metal body, which is formed in the remaining half of the loop from a metal differing from the first metal body. A plurality of junctions are formed between the first metal body and the second metal body of each thermocouple. The junctions are formed at 180.degree. intervals along the spiral thermocouple assembly.
