A fuel injector for use with an internal combustion engine, including a valve housing having one end formed with a fuel injection hole; a valve member reciprocally movable in the valve housing for opening and closing the fuel injection hole; an actuator for effecting reciprocal movement of the valve member; and a nozzle fixedly mounted to the one end of the valve housing and formed with a fuel atomizer passage. The fuel atomizer passage includes a fuel inlet communicated with the fuel injection hole for inducing the fuel injected from the fuel injection hole, a passage portion inclined at a predetermined angle with respect to a direction of injection of the fuel to be injected from the fuel injection hole and having a uniform cross section over the entire length thereof, which passage portion has a fuel colliding portion for allowing collision of the fuel injected from the fuel injection hole, and a fuel outlet for discharging the fuel atomized in the passage portion and for restricting a divergence and a direction of a fuel spray to be discharged therefrom.
