摘要
A thermoelectric conversion module (10) comprises a first electrode member (13) arranged on a low temperature side, a second electrode member (14) arranged on a high temperature side, and p-type and n-type thermoelectric elements (11 and 12) arranged between and connected electrically with both the first and second electrode members (13 and 14). The thermoelectric elements (11 and 12) are composed of a thermoelectric material (half-Heusler material) containing an intermetallic compound having an MgAgAs crystal structure as a main phase and have a fracture toughness value K1C of not less than 1.3 MPa·m1/2 and less than 10 MPa·m1/2.
