PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of promoting the atomization of a fuel by positively forming cavitation bubbles. SOLUTION: The fuel injection valve 1 has an injection hole 7 formed in a nozzle body 3 and bent in a bent portion 15 located between an inlet 10 and an outlet 11, and a cavitation room 16 for generating cavitation bubbles in the fuel flowing in the injection hole 7 due to the expansion of the flow path is formed inside the bent portion 15 so as to communicate with the injection hole 7, in the nozzle body 3.
