To perform excellent atomization of fuel during a time between the initial stage of fuel injection and completion thereof.

In a fuel injection valve having a needle 2 to repeat injection and the stop of a fuel by opening and closing a gap formed between a seat surface 8 and a seat surface 9 formed at the tip part of a nozzle body 10, atomization of fuel is promoted by providing a swirl flow generating means consisting of an oblique groove 3, formed in a spot located at upper stream of the gap and generating a swirl flow of fuel, and an eccentric needle protrusion part 13 arranged at the tip part of the needle 2 located at downstream of the gap.
