PROBLEM TO BE SOLVED: To provide an injector which can prevent an injection timing of a fuel from coming out of place. SOLUTION: The injector (1) is provided with an electromagnetic operating valve (10) to control the fuel injection. The electromagnetic operating valve is provided with a valve body (17) having passages (17a, 17b and 17c) of the fuel, an armature (16) to open and close the passages of the fuel, and an exciting coil (13) to open and close the electromagnetic operating valve by displacing the armature with excitation. The armature is provided with a plate-like wing (16e). The valve body is provided with four openings (17c) which opens to an end face (17d) of the valve body in which the passages of the fuel are opposite to the wing. Three notches (16g) are provided in the wings to able to circulate the fuel from the openings. This structure makes the area of the wings not opposed to the openings substantially stable notwithstanding the relative position of the valve body for the notches of the wing.
