To prevent improper flow of fluid when a solenoid valve is opened and realize high speed operation simultaneously.
A valve element is divided into a check valve body 80 and an armature 94. The check valve element 80 is attached to a valve body section 72 in such a manner that it can slide in a scope of a predetermined stroke and has a seat section 81 which adheres or is separated from a valve seat section 78 formed in the valve body section 72. By receiving fluid pressure on a high pressure side as pushing pressure in the direction in which a valve is closed, the armature 94 is attached to an actuator holder section 73 in such a manner that it can move in a scope of a stroke which is smaller than the stroke of the check valve element 80. When it comes into contact with the check valve element 80 in such a manner that it can come into contact with and be separated from it, the check valve element 80 is stopped at a degree of opening which is below fully open degree, and the stroke of the armature 94 is smaller than the stroke of the check valve element 80.
