Abstract
A thermoelectric material includes a composition represented by the following formula (A):(TiZrHf)NiSn  (A)where 0<a1<1, 0<b1<1, 0<c1<1, a1+b1+c1=1, 30≦x≦35, and 30≦y≦35. The composition includes at least two MgAgAs crystal phases different in a lattice constant, and, assuming that X-ray diffraction peak intensity from a (422) diffraction plane of a first MgAgAs crystal phase having a smallest lattice constant and X-ray diffraction peak intensity from a (422) diffraction plane of a second MgAgAs crystal phase having a largest lattice constant be Iand I, respectively, a value of I/(I+I) is in a range of 0.2 to 0.8.
