An object of the invention is to provide a fuel injection valve that applies a swirl to an upstream side of a seat section to shorten spray penetration.When flows into injection hole entries are indicated by arrows 101a to 106a and injection hole exit directions are indicated by arrows 201 to 206, an angle α defined by the inflow direction 101a and the exit direction 201 of an injection hole 71 can be increased. In a method for applying the twisted angle α, a side groove 15a on an outer peripheral side of a guide member 12a is set to be accompanied with a twist with respect to an axis O1. Furthermore, a flow passage area of the side groove 15a is set smaller than a flow passage area on an upstream side of the guide member 12a and is also set larger than a flow passage area of a seat section 7B that is constructed by a gap between a valve body 7 and an orifice cup 7.
