PROBLEM TO BE SOLVED: To provide a fuel injection nozzle 1 for conducting injection-supply of fuel to an engine in which diffusibility of injected fuel is improved. SOLUTION: A 1st and a 2nd nozzle holes 2, 3 respectively are provided axially in the same line in the axial direction of the fuel injection nozzle 1 so that respective axes are not parallel, and are twisted without intersection. Thus, jets from the 1st and the 2nd nozzle holes 2, 3 interfere with each other without coming into collision. Since the 1st and the 2nd nozzle holes 2, 3 are twisted, injection flows from the nozzle holes 2, 3 are diffused swirlingly. Thus, the injection fuel is diffused in a more widespread space than in the case where the axes of the 1st and the 2nd nozzle holes 2, 3 are set parallel to allow the jets to interfere parallel with each other, and in the case where the axes of the 1st and the 2nd nozzle holes 2, 3 are set so as to intersect so that the jets are allowed to collide and diffused unidirectionally at a wide angle.
