PROBLEM TO BE SOLVED: To provide a solenoid valve with a movable core less in staggering when slid. SOLUTION: The solenoid valve comprises a body member 12 having a given sliding guide space 12a, a fixed core 14 for closing the body member 12 at one end, the movable core 16 slidable in the sliding guide space 12a between the fixed core 14 and a valve seat body 20 stored in the body member 12, an energizing member 15 provided for abutting on the fixed core 14 and the movable core 16 to give energizing force to the movable core 16 to the side of the valve seat body 20, and a valve element 18 provided at the end of the movable core 16 at the side of the valve seat body 20 for closing the valve with the movable core 16 energized by the energizing member 15 and seated on the valve seat body 20. The movable core 16 has a storage space 16a for the energizing member 15 opened to the end on the side of the fixed core 14, and the energizing member 15 abuts on the movable core 16 in the storage space 16a. At least in the valve closed condition, a position where the energizing member 15 abuts on the movable core 16 is on the side of the valve element 18 beyond an intermediate position C1 in the sliding direction of the movable core 16 in a slide contact area 16e of the movable core 16.
