The present invention provides a thermoelectric conversion material that is a material comprising elements less poisonous than Te and has a Seebeck coefficient comparable to BiTe. The present invention is a full-Heusler alloy that is represented by the composition formula Fe 2+Ã Ti 1+y Si 1+z and has Ã, y, and z allowing the material to fall within the region surrounded by (Fe, Ti, Si) = (50, 37, 13), (50, 14, 36), (45, 30, 25), (39.5, 25, 35.5), (54, 21, 25), and (55.5, 25, 19.5) by at% in an Fe-Ti-Si ternary alloy phase diagram. |
