A thermoelectric generator unit includes: a case having a heating surface and a cooling surface; first to fourth thermoelectric generator modules housed in the case, the thermoelectric generator modules including a plurality of thermoelectric elements; a multilayer substrate including: a first layer including an interelement electrode for forming an output circuit configured to connect the thermoelectric elements; a second layer provided with a plurality of through holes penetrating therethrough from front to back; and a third layer including a plurality of bypass patterns electrically continuous with the through holes; and lead pins that penetrate through the case inward and outward, the lead pins having base ends connected to both ends of the output circuit on a surface of the first layer, the output circuit being defined in each of the thermoelectric generator modules.

Thermoelectric generation unit

A thermoelectric module includes a low temperature-side wiring line, a high temperature-side wiring line, a low temperature-side member, a plurality of low temperature-side thermoelectric conversion elements made of a BiTe-based material, a high temperature-side member, a plurality of high temperature-side thermoelectric conversion elements made of a material different from the BiTe-based material, an insulating member, a radiant heat blocking plate, a low temperature-side electrode, and a high temperature-side electrode. The radiant heat blocking plate is arranged on the side of the high temperature-side member with respect to the low temperature-side wiring line and the high temperature-side wiring line. A thermoelectric module that can restrain burning of wiring lines, as well as a thermoelectric power generating apparatus and a thermoelectric generator including the same can thereby be obtained.
