SOLUTION: A downward passage 17 that directs downward from the outer periphery of an atomization collision room 16 toward a sack portion 13 is made at the tip end 15 projecting from the tip of a fuel injection nozzle. A sideways passage 18 is made that directs the atomization collision room 16 from the side surface of the tip end 15 and intersects the downward passage 17 and the portion from the intersection point to the exit side is clogged by a filler 19. Therefore, when a needle valve 11 is moved, the fuel is injected into the atomization collision room 16 via the sack portion 13 and passages 17, 18.  In this respect, the fuel injected from the opposite sideways passages 18 collides with each other to accelerate atomization and, when atomized fuel after collision is discharged from the atomization collision room 16, the volume of the atomized fuel is increased to form a uniform lean mixture.
