(57) [Problem] To provide a method for producing a thermoelectric conversion material in which the carrier density is low, the mobility is high, and the figure of merit is greatly improved. SOLUTION: This is a method for producing a thermoelectric conversion material, in which at least two or more of bismuth, tellurium, selenium and antimony and, if necessary, a dopant are mixed and melted, and the obtained alloy lump is pulverized and then hot pressed. , the milling and hot pressing C n H 2n + 1 OH or C n H 2n + 2 CO A method for producing a thermoelectric conversion material, wherein the method is performed in the presence of a solvent represented by (n is 1, 2 or 3). |
