<p>The present invention relates to a solenoid valve. The solenoid valve operates a vacuum actuator which circulates a valve disposed inside a runner in order to change an air inhalation pathway in the runner of an intake manifold of a vehicle. The solenoid valve comprises: a bobbin in which an inhale port and an exhaust port are integrally formed on one side to allow connection; an armature which is inserted into the other side of the bobbin and is disposed to be able to move in the axial direction in the vicinity of an exhaust port inner end; and a coil which is wound on the outer periphery of the bobbin and moves the armature in the axial direction by generating electromagnetic force when a current is applied. It is desirable that negative pressure is generated in the vacuum actuator by the negative pressure of the intake manifold since the intake manifold is connected to the exhaust port and the inhale port is connected to the vacuum actuator.</p>
