PROBLEM TO BE SOLVED: To provide a solenoid operating valve for an injector capable of reducing cost by reducing the number of parts and capable of expanding magnetic pole area by expanding attraction surface of a stator. SOLUTION: The solenoid operating valve 10 is provided with a housing 11, the stator 14 having an exciting coil 13 built therein and including the attraction surface 16a on a lower surface, an armature 16 arranged to face the stator 14, a stopper member 15 fitted in the stator 14. An outer circumference surface of the stator 14 is fitted in an upper part 3a of an injector body 3, and the stator 14 is gripped by a lower surface of the housing 11 at an upper part and a gripping surface 15c of a stopper member 15 at a lower part to be retained in an axial direction. The attraction surface 16a is formed on a part of the armature 16 facing the attraction surface of the stator 14, and a projection ring 16c projecting from the attraction surface 16c is formed on a part facing a lower surface of the stopper member 15 to regulate movement of the armature 16.
