Abstract:
A thermoelectric module comprising:a case; a heat-radiation side insulating substrate; a heat-absorption side insulating substrate; a first soldering layer formed of a first soldering agent at a position to connect the heat-radiation side insulating substrate and the case; a plurality of P-type and N-type semiconductor chips interposed between the heat-radiation side insulating substrate and the heat-absorption side insulating substrate, the plurality of P-type and N-type semiconductor chips being arranged alternately to be connected in a series; and a second soldering layer formed of a second soldering agent at a position to connect the heat-radiation side insulating substrate and one end of each of the plural P-type and N-type semiconductor chips, the second soldering layer also connecting the heat-absorption side insulating substrate and the other end of each of the plural P-type and N-type semiconductor chips, the second soldering agent being identical with the first soldering agent in raw material.
