Abstract: In an automotive anti-lock brake control system, solenoid portions of electromagnetic valves and an electronic control unit for controlling the energizing of an electric motor are accommodated in a cover which is joined to a housing. Provided on the substrate of the control unit are a positive side conductive line having a relay circuit interposed at a position along the length thereof and connected to the motor, and a negative side conductive line connected to the motor and allowed to function as a negative side power supply line for the substrate. The positive and negative side conductive lines are connected to ends of a battery via motor coupler terminals. A capacitor electric component acting as a countermeasure against the noise attributed to the electric motor is mounted on the substrate so as to provide a connection between the positive and negative side conductive lines.
