Abstract: An opening intersection point is between a nozzle hole axis and an inlet opening portion. A normal line of a suction wall surface at the opening intersection point intersects a nozzle hole inner wall or an imaginary inner wall which is an extension of the nozzle hole inner wall. A distance from an outlet opening portion to an inner wall intersection point, which is an intersection point between the normal line and the nozzle hole inner wall or the imaginary inner wall, is LA. An nozzle hole length between the inlet opening portion and the outlet opening portion of the nozzle hole inner wall on a side where the inner wall intersection point is formed is LB. The nozzle hole is provided such that LA/LB>−0.2.
