Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress variations of an injection mode in a fuel injection nozzle that injects a fuel to an internal combustion engine.SOLUTION: According to a nozzle 1, an opening 11a of an injection hole 11 exists closer to the front end in an axial direction than a tip 2d of a needle 2 when a seat part 13 is seated at a seat position 10. This relaxes the influence exerted on an injection mode by a flow state of a fuel in a sack chamber 21 so as to suppress variations of the injection mode.
