An object of the present invention is to provide a thermoelectric conversion module which is obtained by combining an insulating member, a heat dissipation member, or the like with a bellows-like thermoelectric conversion module and has good structural stability and handleability and good flexibility, a heat conductive laminate used for the thermoelectric conversion module, and methods of producing the same. The object is achieved by providing a thermoelectric conversion module including a module main body having a bellows-like support, thermoelectric conversion layers formed on the support and are separated from each other, connection electrodes which connect the thermoelectric conversion layers adjacent to each other; one or more bellows-like members provided such that concave and convex portions thereof are fitted to those of the module main body; and a flexible linear member which penetrates sloped surfaces of a bellows of the module main body and sloped surfaces of a bellows of one or more bellows-like members so as to be inserted through the module main body and the one or more bellows-like members.
