In an electromagnetic valve in which a valve body unit is housed in a housing, the unit has a plunger including a groove portion at its cylindrical outer peripheral face. The groove portion extends in the cylinder axis direction and moves in the cylinder axis direction by an electromagnetic force generated by an electromagnetic coil. A rod is secured to the plunger and abuts against a valve seat for opening and closing the valve when the plunger is moved to close the valve and releasing the abutment of the rod against the seat when the plunger is moved to open the valve. A cylindrical sleeve covers the outer peripheral face of the plunger and is configured integrally with the plunger. A communication passage defined by the groove portion of the plunger and the inner peripheral face of the sleeve extends in the cylinder axis direction.
