PROBLEM TO BE SOLVED: To obtain a fuel injection valve capable of injecting fuel in the form of a liquid film and stably atomizing a high flow rate of the fuel with a simple structure.SOLUTION: Four injection holes 16a and four injection holes 16b are arranged on two pitch circles about a hole center of a valve hole 14d of an injection hole plate 15 and having different radii, respectively, the injection hole 16a satisfying a relation of r<(5/4)*(d/h) is present only in one rotation direction if a plane Ph passing through a hole center of the injection holes 16a and including the hole center of the valve hole 14d rotates about the hole center of the valve hole 14d, a plane Ps that includes the hole center of the valve hole 14d and about which the eight injection holes 16a and 16b disposed in the injection hole plate 15 are mirror-image symmetrical is present, and the injection holes 16a and 16b are not disposed on the plane Ps. |
