Claim 19:
20. A thermoelectric conversion module member comprising a thermoelectric conversion layer and a diffusion prevention layer in direct contact with said thermoelectric conversion layer, wherein
said thermoelectric conversion layer is a layer containing a thermoelectric conversion material having a silicon element or a tellurium element,
said diffusion prevention layer is a layer containing a metal and the same thermoelectric conversion material as the thermoelectric conversion material contained in said thermoelectric conversion layer, and
the amount of said thermoelectric conversion material in said diffusion prevention layer is 10 to 50 parts by weight with respect to 100 parts by weight of said metal,
wherein the diffusion prevention layer has a uniform composition comprising the metal and the thermoelectric conversion material, and
wherein the thermoelectric conversion module member has only one diffusion prevention layer.
