A thermoelectric material, which has a superior thermoelectric characteristic and is environment-friendly and is suitable for mass productivity due to the lower cost, is provided. The thermoelectric material is an iron alloy that mainly contains Fe, V and Al and that carbides are dispersed into the matrix, wherein [V concentration -C concentration] is 20 or more at% to 32 or less at% and [Al concentration + Si concentration] is 20 or more at% to 30 or less at%. Especially in the thermoelectric material of the present invention, a high Seebeck coefficient can be kept and a lower electrical resistivity can be obtained, thereby improving an output factor and achieving a superior thermoelectric characteristic.
