To disclose a circuit unit in an onboard electrical component with a novel structure that can simplify the structure of the enclosure of the onboard electrical component and reduce misalignment due to tolerances in the connection position between the connector and the circuit unit.SOLUTION: A circuit unit 10 has a retainer 14 that holds the circuit member 12, a plate wall 104 that covers the enclosure through-hole 156 of the onboard electric component 130, a connector 118 with a connection member 114 that is held by the plate wall 104, and a sealing member 126 that is provided on the first surface 110 being the surface of the plate wall 104 that is attached to the enclosure 132, and contacts the periphery of the enclosure through-hole 156, the circuit side connection 120 protruding from the first surface 110 side of the connection member 114 can be detachably connected to the circuit member 12, and the circuit side connection 120 is connected to the circuit member 12 by being inserted into the enclosure through-hole 156 from outside the enclosure 132, and the seal member 126 contacts the peripheral edge of the enclosure through-hole 156 from the external side of the enclosure 132.SELECTED DRAWING: Figure 2

    【課題】車載電気部品の筐体の構造を簡素化でき、コネクタと回路ユニットの接続位置の公差による位置ずれを低減することができる、新規な構造の車載電気部品内回路ユニットを開示する。【解決手段】回路ユニット10が、回路部材12を保持する保持体14と、車載電気部品130の筐体貫通孔156を覆う板壁部104と、板壁部104に保持される接続部材114を有するコネクタ118と、板壁部104の筐体132へ取り付けられる面である第1面110に設けられ、筐体貫通孔156の周縁に接触するシール部材126と、を備え、接続部材114において第1面110側に突出する回路側接続部120は、回路部材12に着脱自在に接続可能であり、回路側接続部120が、筐体132の外部から筐体貫通孔156に差し入れられて回路部材12に接続され、シール部材126が筐体132の外部側から筐体貫通孔156の周縁に接触するようになっている。【選択図】図2
