Abstract

A thermoelectric generation unit according to the present disclosure includes a plurality of thermoelectric generation tubes. Each thermoelectric generation tube generates an electromotive force in an axial direction based on a temperature difference between its inner peripheral surface and outer peripheral surface. The thermoelectric generation unit includes a container housing the plurality of thermoelectric generation tubes inside, a plurality of electrically conductive members providing electrical interconnection for the plurality of thermoelectric generation tubes, and a plurality of electrically conductive ring members each receiving an end of a thermoelectric generation tube so as to be in contact with the outer peripheral surface of the thermoelectric generation tube. Each electrically conductive ring member electrically connects the thermoelectric generation tube to a corresponding electrically conductive member.
