Disclosed is a circuit unit in an in-vehicle electrical component, which has a novel structure and is capable of reducing the number of man-hours on the side of the in-vehicle electrical component and reducing the size of the in-vehicle electrical component. A circuit unit (10) in an in-vehicle electrical component is provided with: an insulating holder (28) that holds circuit members (38, 40); a wire harness (34) provided with a covered electric wire (102), a circuit-side connection part (104) provided at one end of the covered electric wire (102), a connector (106) provided at the other end of the covered electric wire (102), and a grommet (108) through which the covered electric wire (102) passes; a panel wall section (32) that covers a housing through-hole (180) provided in a housing (152) of the vehicle-mounted electrical component (146); and a sealing member (100) that is provided on a first surface (84), which is a surface of the plate wall section (32) to which the plate wall section (32) is attached to the case (152), and that is in contact with the peripheral edge of the case through-hole (180), the wire harness (34) being inserted through a grommet attachment hole (96) of the plate wall section (32), and the grommet (108) of the wire harness (34) being in close contact with the grommet attachment hole (96) to seal the grommet attachment hole (96).
