PROBLEM TO BE SOLVED: To provide a thermo-electric material which has excellent thermoelectric conversion performance even in a temperature range of 300 K or more by improving a composition of a Bi-Te system thermoelectric material.SOLUTION: A thermo-electric material is represented by a composition formula of (BiSb)ATe(where, x:0.15 to 0.25, y:0.75 to 0.85, z+y=1, z:0.006 to 0.02, A:In, Ge, Sn, Al or Ga). In is preferable as A. |
