A thermoelectric power generating device and a power generating system using the same are provided which have easiness in maintenance and require a smaller space and which can perform thermoelectric conversion (power generation) from fluids with different temperatures to conduct electric power supply in a way cheaper and more stable than in the conventional devices. A thermoelectric element 27 constituted by P- and N-type thermoelectric semiconductor elements arranged alternately and sealed in heat transfer plates 30 in a sandwiched manner through electrodes and insulators to provide a plate-like thermoelectric power generating unit 31. A plurality of the units 31 are laminated to alternately form first and second spaces 32 and 33 for communication of high- and low-temperature fluids W and C, respectively, between the units. Openings provided by the respective units 31 are gathered to form first inflow and outflow passages 34 and 35 for inflow and outflow of the high-temperature fluid W to and out of the first spaces 32, respectively, and second inflow and outflow passages for inflow and outflow of the low-temperature fluid C to and out of the second spaces 33, respectively.
