A solenoid valve includes a non-magnetic main body having therein a solenoid coil and core, the core being formed of magnetic material and extending in the coil along the axial direction thereof. A plate member formed of a magnetic material is positioned at one end of the main body along the direction of movement of the core, and is integrally formed with the coil bobbin. A housing member having fluid communication passages therein is positioned adjacent the plate member at a side of the plate member opposite the main body. A valve structure actuatable by the core is positioned between the main body and the housing member for controlling fluid flow in fluid communication passages within the housing member. A yoke member formed of a magnetic material has a U-shaped including arms mechanically secured to the plate member, and has a bent portion mounted to the core.
