A fuel injection valve with high freedom to optimize the direction of fuel spray, the shape of spray, the length of penetration, the existence/absence of lead spray and the like, in correspondence with each type of internal combustion engine is provided. A swirling force about a central axis of an injection orifice is supplied by a swirler to fuel injected from the injection orifice. A central axis E of the injection orifice is slanted at a predetermined deflection angle to a central axis of a valve body. Further, a step portion is formed in an end surface of the injection orifice.
