An on-off valve consisting of a movable slide member and a ball valve attached to its front end is inserted, and the slide member has a flange-shaped slide portion that is slidable in the slide hole and faces at a distance. A gap is formed between the sliding parts, and the opening/closing valve moves back and forth intermittently by electromagnetic force and the spring force, and the ball valve is detached from and contacted with the valve seat part to open and close the fuel injection hole. The electromagnetic fuel injector intermittently injects pressurized fuel from a fuel injection hole, wherein the slide member has a mechanism for communicating the gap with a slide hole in front of the gap. type fuel injector.
