PROBLEM TO BE SOLVED: To provide a gold-tin joint Peltier element thermoelectric conversion module useful for achieving a lead free module when viewing the whole optical communication module and prevention of optical axis deviation of a laser diode.;SOLUTION: A thermo-module 10 is constituted by joining a plurality of pairs of P type thermoelectric semiconductor elements 13a and N type thermoelectric semiconductor elements 13b between a ceramic substrate 11 on the heat dissipation side and a ceramic substrate 12 on the cooling side, and joining a lead wire 15 or a post 16 for power supply to a lead wire mounting land part 112a-1 of the ceramic substrate 11. The lead wire mounting land part 112a-1 of the ceramic substrate 11 and the lead wire 15 or the post 16 are joined with gold-tin layers. As the gold-tin layers 113, 123, gold-tin eutectic composition solder having a gold content of about 80% by weight is used.;COPYRIGHT: (C)2009,JPO&INPIT
