Abstract: A thermoelectric conversion material has a La2O3-type crystal structure and is of n-type. The thermoelectric conversion material has a composition represented by Mg3+m-a-bAaBbD2-e-fEeFf. D is at least one of Sb or Bi. E is at least one of P or As. m is a value of greater than or equal to −0.1 and less than or equal to 0.4. e is a value of greater than or equal to 0.001 and less than or equal to 0.25. A is at least one of Y, Sc, La, or Ce. F is at least one of Se or Te. a and f are values that satisfy a condition of 0.0001≤a+f≤0.06. B is at least one of Mn or Zn. b is a value of greater than or equal to 0 and less than or equal to 0.25.
