Claim 15:
16. The thermoelectric material according to claim 1, wherein a plurality of the chips of the thermoelectric material have a standard deviation of a dimensionless performance index ZT of 0.06 or less at absolute temperatures of 300K and 673K, wherein the dimensionless performance index ZT is a product of a performance index Z of the thermoelectric material multiplied by the absolute temperature T, and the dimensionless performance index Z is represented by a formula (2),

Z=α2σ/κ  (2)

wherein, in the formula (2), α is a Seebeck coefficient of the thermoelectric material, σ is an electric conductivity of the thermoelectric material, and κ is a thermal conductivity of the thermoelectric material.
