To provide a normal open type solenoid valve which has advantage in common parts and assembling property by commonizing a position of a spring member and its energizing direction in respect to the normal open type solenoid valve.
A valve part 21c of a movable iron core 20 is normally opened by means of a valve member 25. One end 8a of a spool hole 8 of a spool 7 is faced to an inlet passage 2. A valve port 16 is formed on the side of the other end 8c of the spool hole 8 so as to be spaced from the inlet passage 2. A fixed iron core 9 is arranged on the side of the end 8c of the spool hole 8, while a movable iron core 20 is arranged between the inlet passage 2 and the fixed iron core 9. The spring member 25 is arranged with longer space to the inlet passage 2 than the movable iron core 20 so as to provided the spring member 25 with energizing force directed from one end 7c of the spool 7 to the other end 7a.
