PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of promoting atomization of fuel droplets injected through a plurality of injection holes to the outside.SOLUTION: A fuel injection valve includes an injection hole plate 30 having a plurality of injection holes 31. Each injection hole 31 is oval-shaped with its flow path cross section having a first axis and a second axis, and taper-shaped so that its flow path cross section area is gradually larger as extending from an entry side opening end 31a to an exit side opening end 31b. Directions of axis lines Z of the injection holes 31 are set so that adjacent outer edge portions of spray ranges of fuel injected through the injection holes 31 are lined parallel to fuel injecting directions. |
