THERMOELECTRIC CONVERSION DEVICE

PROBLEM TO BE SOLVED: To provide a thermoelectric conversion device capable of enhancing intensity while facilitating miniaturization.SOLUTION: A thin-walled copper plate is drawn to form a lower side and an upper side cases having recess parts on their central parts and flange like outward flange parts around them. A plurality of dice like thermoelectric elements are arranged longitudinally and horizontally to form a rectangular thermoelectric module which are integrally formed with each other by an adhesive containing insulation particles, and the thermoelectric module is received in both opposing recess parts of both cases. Belt-like terminals connecting each of thermoelectric elements in series are provided on bottom surfaces of each recess parts, and lead lines are connected to dummy elements at two corners of thermoelectric modules. It is possible to downsize the whole, to reduce an area of bottom surface of the recess part provided on the case for receiving a plurality of thermoelectric elements and conductive relay members, and to enhance strength of the whole case because a space is not caused in a part where thermoelectric elements and conductive relay members are arranged in the case.
