PROBLEM TO BE SOLVED: To improve the spray angle, diffusion of spray, and atomization of a fuel injection valve, and to realize appropriate penetration of spray. SOLUTION: A slit-shaped injection nozzle is in the range of 0-90 deg. in the angleβin the opening direction relative to the axis of a fuel injection valve relative to a longitudinal wall part extending from an inner end 9 to an outer end 10, and formed expanded outward of the place to connect the axis of the fuel injection valve and the inner end 9, and the width W of the inner end 9 is in the range of 0.05-0.24mm to promote atomization of spray.
