<p><P>PROBLEM TO BE SOLVED: To provide a reliable multistage thermoelectric module by electrically connecting a thermoelement at a thermoelectric conversion section in each stage by a method having high durability. <P>SOLUTION: A plurality of first-stage n-type thermoelements and a plurality of first-stage p-type thermoelements are alternately arranged while they are adjoined one another and are connected in series by joining to a plurality of copper electrodes formed on the facing surface between a radiation-side substrate 4h and a sublevel substrate 4m for clamping. A plurality of first-stage n-type thermoelements and a plurality of first-stage p-type thermoelements are alternately arranged while they are adjoined one another and are connected in series by joining to a plurality of copper electrodes formed on the facing surface between the sublevel substrate 4m and a heat-absorption-side substrate 4c for clamping. Then, a rectangular notch 5 is provided at the edge of the sublevel substrate 4m, one edge of a pair of thermoelements 1 for connection is joined to the copper electrode on the heat-radiation-side substrate 4h, and the notch 5 is pierced for joining the other edge to the copper electrode of the heat-absorption-side substrate 4c, thus electrically connecting the thermoelement 2 at a first-stage thermoelectric conversion section 15 to the thermoelement 3 at a second-stage thermoelectric conversion section 16 in series. <P>COPYRIGHT: (C)2004,JPO</p> |
