摘要： According to the present invention, a thermoelectric conversion material that is capable of exhibiting good thermoelectric conversion performance is obtained using a silicon-based material. This thermoelectric conversion material is characterized in that: columnar or spherical nanodots 1 having diameters of 20 nm or less are embedded in an embedment layer 3 at an area density of 5 × 10 10 pieces/cm 2 or more and at intervals of from 0.5 nm to 30.0 nm (inclusive); a first material constituting the nanodots 1 contains 30 atom% or more of silicon; and, with respect to a second material constituting the embedment layer 3, the energy difference between the valence band of the first material and the valence band of the second material and/or the energy difference between the conduction band of the first material and the conduction band of the second material is within the range from 0.1 eV to 0.3 eV (inclusive).
