PROBLEM TO BE SOLVED: To provide a circuit structure capable of inhibiting the occurence of common mode noise.SOLUTION: A circuit structure 20 includes: a circuit board 23 having a conducting path; switching elements S1 to S4 which turn on or off an energizing current of the circuit board 23; a conductive heat radiation member 35 which is overlapped with the circuit board 23 through an insulation layer and is electrically connected with ground; capacitors 31 to 33 for measures on common mode noise which are connected to points between the conductive path in the circuit board 23 on which the energizing current flows and the heat radiation member 35.

    【課題】コモンモードノイズの発生を抑制することが可能な回路構成体を提供する。【解決手段】回路構成体20は、導電路を有する回路基板23と、回路基板23の通電電流をオンオフするスイッチング素子S1〜S4と、絶縁層を介して回路基板23に重ねられ、グランドに電気的に接続される導電性の放熱部材35と、回路基板23における通電電流が流れる導電路と放熱部材35との間に接続されたコモンモードノイズ対策用コンデンサ31〜33と、備える。【選択図】図3
