THERMOELECTRIC CONVERSION MODULE, ITS MANUFACTURING METHOD, AND THERMOELECTRIC CONVERSION MATERIAL USED FOR THERMOELECTRIC CONVERSION MODULE

摘要

PROBLEM TO BE SOLVED: To provide a thermoelectric conversion module having high long term reliability by suppressing the deterioration of thermal performance caused by the usage and breakage of the thermoelectric conversion module. SOLUTION: A plurality of P-type and N-type thermoelectric conversion elements 5 (5a, 5b) are connected via a solder 9 and an electrode 2 to form a circuit of the thermoelectric conversion elements 5 (5a, 5b). For example, a Peltier module wherein one end side of the thermoelectric conversion elements 5 (5a, 5b) is made to be an endothermic side surface and the other end side is made to be a heat-dissipating side surface according to the direction of a current fed through the circuit is formed. The thermoelectric conversion elements 5 (5a, 5b) are formed by adding at least one of Ag and Cu to a thermoelectric conversion material which contains Bi and Te as main raw materials and at least one of Se and Sb is added thereto.
