To provide a fuel injection valve with a simple structure capable of easily carrying out a processing and an accuracy taking, suppressing pulse pressure of fuel generated at the time of an opening/closing action of valve part and reducing a noise caused by the pulse pressure.
A fuel passage 37 is formed in a housing 16 of a fuel injection valve 11 mounted to an engine. A fuel suction port 20a is provided on one end of the fuel passage 37 and an injection port 21b is formed on the other end. A valve part 18 for injecting a fuel suctioned by opening/closing the injection port 21b from the fuel suction port 20a to a combustion chamber of a cylinder head 12 is provided on the housing 16. An enlarged part 39 of which a passage cross section is enlarged is provided on the way of the fuel passage 37 from the fuel suction port 20a to the injection port 21b.
