A solenoid valve includes a coil assembly accommodated in a solenoid housing having an end wall at one end thereof. A stationary core is magnetically coupled to the end wall and inserted into one end of a center bore, and a movable core opposed to the stationary core is inserted into the other end of the center bore. A yoke plate opposed to the other end of the coil assembly is coupled to the other end of the solenoid housing, and a collar made of a non-magnetic material adapted to guide the axial movement of the movable core is inserted into the other end of the center bore through a central portion of the yoke plate. A rod operatively connected to the movable core is connected to a valve member accommodated in a valve housing connected to the solenoid housing. In such solenoid valve, in order to facilitate the processing and assembling of the collar, the movable core and the rod and to provide a reduction in cost, the valve housing is provided with a guide for guiding the axial movement of the rod, and one end of the rod is put into coaxial abutment against the other end of the movable core.
