Disclosed is a circuit unit in an in-vehicle electrical component having a novel structure, which can simplify the structure of a housing of the in-vehicle electrical component and can reduce a positional offset caused by a tolerance in the connection position of a connector and the circuit unit. A circuit unit (10) is provided with: a holding body (14) that holds a circuit member (12); a plate wall section (104) that covers a housing through-hole (156) of an in-vehicle electrical component (130); a connector (118) that has a connection member (114) held by the plate wall section (104); and a sealing member (126) that is provided on a first surface (110), which is a surface of the plate wall section (104) that is attached to a housing (132), and that is in contact with the periphery of the housing through-hole (156). A circuit-side connection part (120) protruding toward the first surface (110) at the connection member (114) is detachably connected to the circuit member (12), the circuit-side connection part (120) is inserted into the housing through-hole (156) from the outside of the housing (132) and is connected to the circuit member (12), and the sealing member (126) is in contact with the peripheral edge of the housing through-hole (156) from the outside of the housing (132).

    公开一种构造新颖的车载电气部件内电路单元,其能够简化车载电气部件的壳体的构造、并能够降低连接器与电路单元的连接位置的公差所导致的位置偏移。电路单元(10)具备保持电路构件(12)的保持体(14)、覆盖车载电气部件(130)的壳体贯通孔(156)的板壁部(104)、具有保持于板壁部(104)的连接构件(114)的连接器(118)以及设置于板壁部(104)的向壳体(132)安装的面即第1面(110)并与壳体贯通孔(156)的周缘接触的密封构件(126),在连接构件(114)处向第1面(110)侧突出的电路侧连接部(120)能够装卸自如地连接到电路构件(12),电路侧连接部(120)从壳体(132)的外部插入到壳体贯通孔(156)并连接到电路构件(12),密封构件(126)从壳体(132)的外部侧与壳体贯通孔(156)的周缘接触。
