Zusammenfassung:PROBLEM TO BE SOLVED: To suppress pressure loss of injected fuel as much as possible in a fuel injection valve and improve the penetration performance. SOLUTION: In this fuel injection valve, a fuel guiding member 40 facing a valve hole 7 is continued to an injector plate 10, and an annular diffusion chamber 39 is formed between a valve seat member 3 and the injector plate 10. On the outer periphery of the fuel guiding member 40, a plurality of notch parts 42 communicating the valve hole 7 with the diffusion chamber 39 and a plurality of closing parts 41 for partially closing the valve hole 7 are arranged alternately at even intervals along the circumferential direction of the fuel guiding member 40, and a plurality of fuel nozzle holes 11 are arranged at even intervals along the circumferential direction of the fuel guiding member 40.
