PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of reducing a generation amount of particulate matters generated at a time of burning fuel.SOLUTION: An injection hole 31 provided in an injection nozzle 30 is formed such that an angle formed between a virtual line VL31 passing through an inner-wall-side center point IP31 provided at a position of a predetermined length R1 from a central axis CA0 and the central axis CA0 is an injection angle α1 and that an angle formed between injection hole inner walls 311 and 312 forming the injection hole 31 is an open angle &bgr;1. Furthermore, an injection hole 32 provided in the injection nozzle 30 is formed such that an angle formed between a virtual line VL32 passing through an inner-wall-side center point IP32 provided at a position of a predetermined length R2 from the central axis CA0 and the central axis CA0 is an injection angle α2. In this case, the injection hole 32 is formed such that an angle formed between injection hole inner walls 321 and 322 forming the injection hole 32 is an open angle &bgr;2 greater than the open angle &bgr;1. It is thereby possible to ensure the atomization of fuel. |
