Abstract
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 sectionis made to flow so as to diffuse from the center of a fuel diffusion chamberB toward the outer circumference and to flow into a nozzle hole, wherein: the nozzle holecomprises a first nozzle hole, and a second nozzle holeand a third nozzle holethat neighbor the first nozzle holeand are separated therefrom in the circumferential direction of the fuel diffusion chamberB; and, if the distance Lbetween the center of the entry-side opening of the first nozzle holeand the center of the entry-side opening of the second nozzle holeis greater than the adistance Lbetween the center of the entry-side opening of the first nozzle holeand the center of the entry-side opening of the third nozzle hole, the exit-side opening of the first nozzle holeis disposed on the inside of an arrangement circleand on the second nozzle holeside of a line segment
