To provide a technique capable of suppressing the generation of a parasitic device that affects the output of a thermoelectric conversion element.SOLUTION: A thermoelectric conversion module includes: a substrate; a thermoelectric film on the substrate; a first electrode on the substrate; a second electrode on the substrate, the second electrode being different from the first electrode in work function; a first lead wire interconnected with an external connection terminal of the first electrode; and a second lead wire interconnected with an external connection terminal of the second electrode. The first electrode and the second electrode are in contact with a same side of the thermoelectric film. A joint between the external connection terminal of the first electrode and the first lead wire, the first lead wire, a joint between the external connection terminal of the second electrode and the second lead wire, and the second lead wire are distant from the thermoelectric film in plan view.SELECTED DRAWING: Figure 1 【課題】熱電変換素子の出力へ影響する寄生デバイスの発生を抑制できる。【解決手段】熱電変換モジュールは、基板と、基板上の熱電膜と、基板上の第１電極と、第１電極と仕事関数が異なる基板上の第２電極と、第１電極の外部接続端子において接合されている第１リード線と、第２電極の外部接続端子において接合されている第２リード線と、を含む。第１電極及び第２電極は、熱電膜の同一面と接触している。第１電極の外部接続端子と第１リード線との接合部、第１リード線、第２電極の外部接続端子と第２リード線との接合部、及び第２リード線は、平面視において熱電膜から離れている。【選択図】図１
