ABSTRACT:
In a solenoid valve, a coil is disposed on the electronic control side, and is resin injection molded integrally with a resin case housing a circuit board on which electronic components are mounted. Before a hydraulic control unit and electronic control unit are connected, an end of a connecting pin of the coil is electrically connected to wiring of the circuit board. A cover 20 of similar material is pressed and welded onto the resin case to assure a waterproof structure around the circuit board. Finally, a magnetic member or magnetic plate, constituting part of a magnetic circuit provided separately from or integrally molded with the resin case is fastened by a bolt to unitarily connect both units.
