PROBLEM TO BE SOLVED: To provide a thermoelectric conversion device capable of efficiently absorbing heat from an outer space, and performing thermoelectric conversion.SOLUTION: A thermoelectric conversion device 10 comprises a thermoelectric conversion element 1, a heat absorbing fin 2, and a sealing member 3. The thermoelectric conversion element 1 generates power due to a temperature difference between one end and the other end. The heat absorbing fin 2 includes a plate-like bottom surface part 21, and a protrusion 22 protruding from a first surface 211 of the bottom surface part 21. The sealing member 3 seals a recess 24 provided on a second surface 212 on the side opposite to the first surface 211 of the bottom surface part 21. The thermoelectric conversion element 1 is arranged so that the one end faces a bottom surface 241 of the recess 24 and the other end faces the sealing member 3, and sealed in the recess 24.SELECTED DRAWING: Figure 1 【課題】効率的に外部空間から熱を吸収し、熱電変換することができる熱電変換装置を提供する。【解決手段】熱電変換装置１０は、熱電変換素子１、吸熱フィン２、および封止部材３を備える。熱電変換素子１は、一端と他端の間の温度差に起因して電力を発生する。吸熱フィン２は、板状の底面部２１と底面部２１の第１面２１１から突起した突起部２２とを有する。封止部材３は、底面部２１の第１面２１１とは反対側の第２面２１２に設けられた凹部２４を封止する。そして、熱電変換素子１は、一端が凹部２４の底面２４１に対向し、他端が封止部材３に対向するよう配置されて、凹部２４内に封止されている。【選択図】図１
