を形成したことを特徴とする電磁流量制御弁。 A valve body having an inner hole, a first port that opens on the inner circumferential surface of the inner hole, a second port that communicates with the first port through the inner hole, and a valve body that slides in the axial direction on the inner circumferential surface of the inner hole. a spool having a slit that can be fitted into the spool and extending in the axial direction from one end; a spring that biases the spool toward the one end; and a spring that biases the spool against the biasing force of the spring in response to an applied control current. An electromagnetic device comprising an axially displacing solenoid and changing the opening area of the first port relative to the inner hole by axially displacing the slit provided in the spool to change the passage area between the first port and the second port. An electromagnetic flow control valve, characterized in that the spool has a tapered surface formed on the outer circumferential surface of the one end side, which is shorter than the slit and becomes smaller in diameter toward the one end.
