Abstract: A thermoelectric material having improved thermoelectric properties and a method for producing the thermoelectric material are provided. The thermoelectric material contains (Mn1-x-yVxFey)Siγ (0.012≦x≦0.045, 0≦y≦0.06, 1.7≦γ≦1.8) and is produced by homogenously melting the raw materials including Mn, Si, and V mixed to a composition of the thermoelectric material, and then solidifying the melted raw materials at a cooling rate of 13 K/hour or less.
