PURPOSE: Thermoelectric materials, a method for improving thermoelectric efficiency thereof, and a supporting body including the same are provided to improve crystallization of the thermoelectric material including bismuth telluride by performing heat treatment using a sealing container which is completely sealed up. CONSTITUTION: Thermoelectric materials including bismuth telluride is prepared. The thermoelectric materials are a nanowire structure or a bulk type structure. The thermoelectric materials including the bismuth telluride is accepted in a sealing container filled with inert gas. The sealed container for accepting the thermoelectric materials is sealed up through alumina paste. The sealed container is filled with tellurium powder and heat treatment is performed.
