Abstract
A method of manufacturing a thermoelectric element capable of varying the temperature characteristics for the figure of merit of the thermoelectric element by changing the conditions during manufacture, the method comprising the steps of mixing and melting by heating starting materials containing substances for controlling the carrier concentration at a predetermined ratio, solidifying the same to prepare an ingot, then powdering the ingot, pressing or press sintering the thus formed powder and further applying hot plastic deformation, in which at least one of the ratio of substances for controlling the carrier concentration or the temperature for carrying out hot plastic working is changed.
