PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of avoiding a collision of fuel with an intake valve, even when injecting the fuel when the intake valve is an opening state, for directly injecting and supplying the fuel into a combustion chamber. SOLUTION: This fuel injection valve 10 directly injects and supplies the fuel into the combustion chamber 106, and injects the fuel when the intake valve 107 is the opening state, and has a valve body 12 having a valve seat 14 on an inner peripheral surface 13, a nozzle port plate 20 arranged on the downstream side of a fuel flow to the valve seat 14 and having a plurality of nozzle ports 21a to 21j injecting the fuel, and a valve member 30 cutting off fuel injection from the nozzle poets 21a to 21j by seating on the valve seat 14 and allowing the fuel injection from the nozzle ports 21a to 21j by leaving from the valve seat 14. Among the plurality of nozzle ports 21a to 21j, a shaft of the nozzle ports 21a, 21b, 21e and 21f turning the injected fuel to the intake valve 107, is dislocated so as to approach a central shaft 108 of the fuel injection valve 10 more than the other nozzle ports 21c and 21d.
