PROBLEM TO BE SOLVED: To suppress a reduction in endurance of a thermoelectric conversion element while enhancing flexibility thereof.SOLUTION: A thermoelectric conversion element comprises: a porous base material having first and second faces and a hole portion; a thermoelectric material part including a thermoelectric material filled in a part of the hole portion; first wiring provided on the first face; and second wiring provided on the second face. At least one wiring of the first wiring and the second wiring is filled in the other part of the hole portion so as to be in contact with the porous base material, and it is joined to the thermoelectric material in the other part of the hole portion.SELECTED DRAWING: Figure 1 【課題】熱電変換素子の柔軟性を高めつつ耐久性の低下を抑制する。【解決手段】熱電変換素子は、第１の面と第２の面と空孔部とを有する多孔質基材と、空孔部の一部に充填された熱電材料を含む熱電材料部と、第１の面上に設けられた第１の配線と、第２の面上に設けられた第２の配線と、を具備する。第１の配線および第２の配線の少なくとも一つの配線の一部は、多孔質基材に接するように空孔部の他の一部に充填され、且つ前記空孔部の他の一部において熱電材料に接合されている。【選択図】図１
