Claim:
1. A solenoid valve comprising: a valve body; a moving core having connected to one end thereof the valve body; a guide tube having slidably inserted thereinto the moving core; a stationary core disposed in an inner circumference of an opposite end portion of the guide tube so as to face an opposite end of the moving core; a valve spring to urge the moving core in a direction away from the stationary core; an electromagnetic coil disposed to enclose the guide tube; and a magnetic plate disposed on the opposite end of the guide tube, whereby the moving core is sucked to the stationary core by a magnetic force transmitted through the magnetic plate to the stationary core due to electric charging to the electromagnetic coil, wherein the guide tube has a caulked portion formed to fix in position the stationary core by engaging the caulked portion with a recessed groove formed on an outer periphery of the stationary core such that, in a state in which the stationary core is fixed in position by the caulked portion, that surface of the stationary core which faces the magnetic plate is either flush with, or is protruding beyond, the opposite end of the guide tube, whereby, by thus disposing the magnetic plate on the opposite end of the guide tube, that surface of the stationary core which faces the magnetic plate is in contact with the magnetic plate.
