ABSTRACT:
A fuel injection valve includes a valve member, a movable core, a fixed core, and a coil. The valve member opens and closes a nozzle hole. The movable core reciprocates with the valve member in a substantially axial direction of the movable core. The fixed core is arranged on the side opposite to the nozzle hole with respect to the movable core. The fixed core opposes to the movable core. The coil generates magnetic force, which attracts the movable core toward the fixed core when the coil is energized. The coil includes a winding. The winding of the coil has an axial section, which is in a polygonal shape. The axial section of the winding is in a substantially oblong shape, in a substantially rectangular shape, or the like.
