Disclosed is a thermoelectric conversion material that exhibits a high thermoelectric conversion properties. The thermoelectric conversion material comprises zinc oxide and is represented by formula (I): Zn(1-x-y)AlxYyO  (I) wherein Zn represents zinc; Al represents aluminum; Y represents yttrium; and x>0, y>0, and x+y<0.1, and has a structure in which at least a part of aluminum and yttrium are present in crystal lattices of and/or interstitial site of crystal lattices of zinc oxide. |
