Abstract

See full text

A high-performance thermoelectric conversion element using an Si-group thermoelectric conversion material, and an thermoelectric conversion element capable of providing a high-out-put power by improving a power generating efficiency, wherein the thermal expansion coefficient of an electrode material is set to up to 10 ppm/K in order to provide a good electrode joining between a p-type thermoelectric conversion material and a n-type thermoelectric conversion material consisting of an Si-group thermoelectric conversion material to thereby ease thermal stress and prevent cracking and breaking at a joining portion, and, in joining, a brazing filler material selected according to a working temperature range is interposed to thereby provide good joining characteristics, reduce an output loss, and improve a heat resistance and a heat-cycle resistance.
