PROBLEM TO BE SOLVED: To promote atomization of fuel as much as possible for a fuel injection valve and achieve a spray shape corresponding to a shape of an injected fuel guide passage. SOLUTION: This fuel injection valve is provided with a fuel nozzle hole 16 having a circle-like cross section. A swirling component is added to fuel to be injected from the fuel nozzle hole 16. The injected fuel guide passage 18 having a flat cross section is connected to the fuel nozzle hole 16 having the circle-like cross section. The fuel injected from the fuel nozzle hole 16 is injected through the injected fuel guide passage 18 so that the fuel can be injected in a predetermined shape, An inlet opening 19 of the injected fuel guide passage 18 connected to the fuel nozzle hole 16 is made to be larger at least partially than an outlet opening 22 of the fuel nozzle hole 16 connected to the inlet opening 19.
