摘要

PROBLEM TO BE SOLVED: To suppress reduction of heat dissipation while facilitating handling of a circuit board.SOLUTION: A circuit structure body 20 comprises: a circuit board 24 including an insulation substrate 25 with which a conducting path is formed on a dielectric plate, and a plurality of bus bars 27A-27D which are stuck on one side of the insulation substrate 25; an insulation layer 31 which is printed on the plurality of bus bars 27A-27D in such a manner that neighboring ones of the plurality of bus bars 27A-27D are connected; a heat dissipation member 34 that overlaps the insulation layer 31 and dissipates heat conducted from the insulation layer 31; and a fixing member 40 for fixing the circuit board 24 and the heat dissipation member 34 while holding the insulation layer 31 between the plurality of bus bars 27A-27D and the heat dissipation member 34.SELECTED DRAWING: Figure 1
