Abstract
A thermoelectric conversion material includes a sintered body including a main phase including a plurality of crystal grains including Ce, Mn, Fe, and Sb and forming a skutterudite structure, and a grain boundary between crystal grains adjacent to each other. The grain boundary includes a sintering aid phase including at least Mn, Sb, and O. Thus, with respect to a skutterudite-type thermoelectric conversion material including Sb, which is a sintering-resistant material, it is possible to improve sinterability while maintaining a practical dimensionless figure-of-merit ZT, and to reduce processing cost.
