METHOD FOR PRODUCING THERMOELECTRIC CONVERSION ELEMENT

摘要

PROBLEM TO BE SOLVED: To simplify the process of a method for producing a small and high density thermoelectric conversion element. SOLUTION: P-type semiconductor plates 51 and n-type semiconductor plates 52 and laid alternately in layers to produce a first multilayer material which is then cut planarly in the direction perpendicular to the laying direction to produce a semiconductor multilayer plate 54. Two or more semiconductor multilayer plates 54 are laid in layer such that the p-type semiconductor of one semiconductor multilayer plate 54 overlaps the n-type semiconductors of two adjacent semiconductor multilayer plates 54 to produce a second multilayer material which is then cut in the direction perpendicular to the laying direction thus producing a semiconductor multilayer plate 55 serving as thermoelectric conversion element. Alternatively, a p-type semiconductor plate 51, an n-type semiconductor plate 52 and a semiconductor multilayer plate 55 having a substantially identical thickness are employed.
