Claim 18:
19. A thermoelectric conversion module member comprising a thermoelectric conversion layer, a diffusion prevention layer in direct contact with said thermoelectric conversion layer, a higher temperature side electrode, and a lower temperature side electrode having a temperature lower than the higher temperature side electrode, 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 placed between said thermoelectric conversion layer and the higher temperature side electrode and 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, and
wherein the diffusion prevention layer has a uniform composition comprising the metal and the thermoelectric conversion material.
