In the present invention, disclosed is a thermoelectric material which includes a material of a composition formula 1 and a material of a composition formula 2. The composition formula 1 is BiM1M2. (The M1 and the M2 is one among Te, Se, or Sb.) The M1 is different from the M2. The composition formula 2 is D. (The dopant (D) is one of Bi, M1, or M2.). [Reference numerals] (AA) End; (S10) Step of manufacturing an ingot by melting a plurality of components consisting of n-type or p-type thermoelectric materials; (S20) Step of manufacturing the powder by crushing the ingot; (S30) Step of adding any one of dopants among a plurality of components in the crushed powder; (S40) Step of sintering the powder in which the dopant is added |
