To provide a technology capable of satisfactorily radiating heat generated in a heating element.SOLUTION: A circuit structure 10 includes a first circuit board 20 having a first surface 21 and a second surface 22, a second circuit board 30 having a third surface 31 and a fourth surface 32, a heating element 40 mounted on the first surface 21 of the first circuit board 20, and a heat radiation member 50 having a body part 52 provided outside the fourth surface 32 of the second circuit board 30. The first circuit board 20 is mounted on the second circuit board 30 so as to make the second surface 22 face the third surface 31. A second conductive part 27 electrically connected to a terminal 42 of the heating element 40 through a first conductive part 25 provided on the first surface 21 is provided on the second surface 22. A heat radiation path for thermally connecting the second conductive part 27 and the body part 52 is provided between the second conductive part 27 and the body part 52.SELECTED DRAWING: Figure 1

    【課題】発熱素子の生じる熱を良好に放熱できる技術を提供することを目的とする。【解決手段】回路構成体10は、第1面21及び第2面22を有する第1回路基板20と、第3面31及び第4面32を有する第2回路基板30と、前記第1回路基板20の前記第1面21に実装された発熱素子40と、前記第2回路基板30の前記第4面32の外側に設けられた本体部52を有する放熱部材50と、を備える。前記第2面22及び前記第3面31が対向するように前記第1回路基板20が前記第2回路基板30に実装される。前記第1面21に設けられた第1導電部25を介して前記発熱素子40の端子42と電気的に接続される第2導電部27が、前記第2面22に設けられる。前記第2導電部27と前記本体部52との間に、前記第2導電部27と前記本体部52とを熱的に接続する放熱経路が設けられている。【選択図】図1
