Abstract
Molten thermoelectric alloy expressed as (Bi, Sb).sub.2 (Te, Se).sub.3 is rapidly cooled at 10.sup.4 to 10.sup.6 .degree. K/second so as to crystallize the thermoelectric alloy, and powder of the thermoelectric alloy is hot pressed under the pressure equal to or greater than 400 kgf/cm.sup.2 at 200 degrees to 400 degrees in centigrade for a time period between {(-T/5)+90} minutes and 150 minutes or at 400 degrees to 500 degrees in centigrade for a time period between 5 minutes and 150 minutes so as to increase the figure of merit by virtue of the strain left in the crystal and/or micro crystal grain.
