PROBLEM TO BE SOLVED: To avoid the breakdown of each part and improve thermoelectric conversion property and reliability by constituting the heat conductive part of a thermoelectric conversion module out of a metallic plate or a metallic layer coated with a ceramic layer. SOLUTION: Heat conducting parts 26H and 26L are constituted of a metallic plate 28 or a metallic layer coated with a ceramic layer 27, so as to materialize electric insulation or good heat conduction between metallic segments 15A and 15B of a thermoelectric covering element 10 and heat conductive parts 26H and 26L. For example, after boring a through screw hole or the like in the required place of the metallic plate 28, the whole surface is flame-coated with Al2 O3 which is high in heat conductivity into a thickness in the range 10μm-50μm to coat it with a ceramic layer 27. Then, the heat conducting part 26H on high temperature side and the heat conducting part 26L on the cooling side made that way are fixed by fixing screws 18 such as insulating ceramic, teflon, or the like, so as to set up a thermoelectric conversion module.
