摘要： A fuel injection valve with reduced adhesion of deposits to a fuel injecting portion and superior in durability is provided. Also provided is a method for machining multi-orifice type fuel injecting portions easily, less expensively, in good surface roughness, in high productivity, and with few variations in shape, accuracy and surface roughness, using inexpensive equipment. The surface roughness of fuel injecting portions comprising orifices and apertures is made Rz 2 μm or less. Apertures are formed by press working so as to each have a plastic-worked surface of Rz 0.2 μm or less in surface roughness and then orifices are formed in the bottoms of the apertures so as to have a plastic-worked surface of Rz 0.2 μm or less in surface roughness. Further, when abrasion resistance of the nozzle is required, the fuel injecting portions are finished to a surface roughness of Rz 2 μm by quenching.
