    • Provided is a circuit assembly having a new structure in which a busbar circuit unit overlapped with a printed circuit board can reliably be fixed regardless of the heating temperature at the time of soldering of an electrical component. In a circuit assembly 10 in which a busbar circuit unit 16 constituted by a plurality of busbars 14 is overlapped with a printed circuit board 12 having a printed wiring 48 and is fixed thereto via an adhesive sheet 20, the plurality of busbars 14 are adhered to the surface of the adhesive sheet 20 in a state in which the busbars 14 are arranged adjacently and spaced apart by gaps, and the gaps 22 between the busbars 14 are filled with the adhesive agent 24. With the adhesive agent 24, press-cut surfaces 30 of the busbars 24 and at least one of the adhesive sheet 20 and the printed circuit board 12 that is exposed from the gaps 22 between the busbars 14 is adhered.
    • 提供一种具有新结构的电路组件,其中与电路元件焊接时的加热温度无关,能够可靠地固定与印刷电路板重叠的母线电路单元。 在由多个汇流条14构成的汇流条电路单元16与具有印刷布线48的印刷电路板12重叠并通过粘合片20固定到其上的电路组件10中,多个汇流条14粘附到 粘合片20的表面处于母线14相邻地布置并间隔开的状态,并且母线14之间的间隙22被粘合剂24填充。利用粘合剂24,压切表面 汇流条24中的30个以及从汇流条14之间的间隙22暴露的粘合片20和印刷电路板12中的至少一个被粘附。
