Claim Text:
1. A thermoelectric conversion module, comprising: a thermoelectric conversion member; and an electrode member, wherein: the thermoelectric conversion member and the electrode member are bonded by a bonding member, the bonding member includes a thermal stress relaxation layer that is bonded to the electrode member to relax a thermal stress, and a diffusion prevention layer that is bonded to the thermoelectric conversion member to prevent diffusion of a constituent component, the Young's modulus of the thermal stress relaxation layer at 25° C. is smaller than that of the thermoelectric conversion members and the electrode members, and the thermal stress relaxation layer is at least one selected from the group consisting of an Ag (50 to 60% by weight)-Cu, Zn (40 to 50% by weight) alloy, an Ag (50 to 60% by weight)-Cu, Zn, Sn (40 to 50% by weight) alloy, a Cu (70 to 90% by weight)-P (5 to 10% by weight)-Ag (5 to 20% by weight) alloy, and a Cu (60 to 85% by weight)-P (5 to 10% by weight)-Ag (5 to 15% by weight)-Sn (5 to 20% by weight) alloy.
