PROBLEM TO BE SOLVED: To provide a thermoelectric power-generating device for efficient recovery of a generated electric power by allowing a temperature difference between a part to be heated and a part to be cooled of a thermoelectric conversion unit which uses a thermoelectric conversion element. SOLUTION: A thermoelectric power-generating device 100 is provided which comprises a thermoelectric conversion unit provided with a part to be heated and a part to be cooled, a heating air path where a heating air passes which heats the part to be heated, and a cooling air path where a cooling air passes which cools the part to be cooled. Here, a ventilation pipe 40 is provided which communicates with an air outlet 31 of the cooling air path and guides, upward, the cooling air which has passed the cooling air path. Since the density of the cooling air which has passed the cooling air path is lower compared with the outside air, the speed at which the cooling air passes the cooling air path is raised by guiding upward the cooling air of lower density by a ventilation force using the ventilation pipe 40.
