Abstract: At least one of nozzle holes is provided as a non-circular nozzle hole where the ratio of the longest diameter to the shortest diameter of an outlet opening portion is greater than 1. A virtual non-circular cone and a virtual circular cone are defined for each of the non-circular nozzle hole and a circular nozzle hole where the ratio of the longest diameter to the shortest diameter of the outlet opening portion is 1. At least two adjacent nozzle holes are formed such that the virtual non-circular cone does not interfere with the virtual circular cone or the virtual non-circular cone.
