To disclose a circuit unit in an on-vehicle electrical component, the unit having a new structure, that is capable of reducing working man-hours on an on-vehicle electrical component side, and of down-sizing the on-vehicle electrical component.SOLUTION: A circuit unit 10 in an on-vehicle electrical component includes: an insulating holding body 28 for holding circuit members 38 and 40; a wire harness 34 comprising a coated electric wire 102, a circuit side connection part 104 provided at one end portion of the coated electric wire 102, a connector 106 provided at the other end portion of the coated electric wire 102, and a grommet 108 through which the coated electric wire 102 passes; a plate wall part 32 for covering a housing through-hole 180 provided on a housing 152 of the on-vehicle electrical component 146; and a seal member 100 coming into contact with a circumference of the housing through-hole 180, that is provided on a first surface 84 as a surface attached to the housing 152 of the plate wall part 32. The wire harness 34 passes through a grommet attachment hole 96 of the plate wall part 32, and the grommet 108 of the wire harness 34 is closely attached to the grommet attachment hole 96 to seal the grommet attachment hole 96.SELECTED DRAWING: Figure 2
