The purpose of the present invention is to provide a fuel injection valve that can achieve sufficient atomization even if the spray angle is narrow. The present invention is a fuel injection valve, in which fuel flowing in from a fuel passage section 5c is made to flow so as to diffuse from the center of a fuel diffusion chamber 6B toward the outer circumference and to flow into a nozzle hole 7, wherein: the nozzle hole 7 comprises a first nozzle hole 7b, and a second nozzle hole 7d and a third nozzle hole 7a that neighbor the first nozzle hole 7b and are separated therefrom in the circumferential direction of the fuel diffusion chamber 6B; and, if the distance L4 between the center of the entry-side opening of the first nozzle hole 7b and the center of the entry-side opening of the second nozzle hole 7d is greater than the adistance L1 between the center of the entry-side opening of the first nozzle hole 7b and the center of the entry-side opening of the third nozzle hole 7a, the exit-side opening of the first nozzle hole 7b is disposed on the inside of an arrangement circle 101 and on the second nozzle hole 7d side of a line segment 107.
