Abstract
The n-type thermoelectric material has a composition represented by (ABCD)CoFeSb. In the composition, 0≦a≦0.5, 0≦b≦0.7, 0<c≦0.5, a+b+c+t=x, 0.4≦x≦1.0, 0≦y≦0.5, a+b>0; Element A is Mg, Ca, Sr and/or Ba; Element B is Y, Sc and/or La to Lu; Element C is Al, Ga and/or In; and Element D is Zn and/or Ti. The ABCD(=R) satisfies R=[BaA'][YbB′][InC′]D. In the formula, 0<d≦1, 0≦e≦1, 0<f≦1, ad+be>0; Element A′ is the element A other than Ba; Element B′ is the element B other than Yb; and Element C′ is the element C other than In. The n-type thermoelectric material contains five or more kinds in total of the element A to the element D.
