Abstract:
In order to provide an Fe2TiSi type full-Heusler thermoelectric conversion material having a high dimensionless figure-of-merit ZT, the full-Heusler thermoelectric conversion material is characterized in that: the full-Heusler thermoelectric conversion material has secondary crystal grains having an Fe2TiSi type composition and a coating layer covering the circumference of the secondary crystal grains and containing an element other than Fe, Ti, and Si as a main component; and the coating layer has a composition containing an element being dissolvable in a crystal structure of the Fe2TiSi type composition and having an electric resistivity lower than the secondary crystal grains.
