PURPOSE: To provide a fuel impingement part with high accuracy for improving atomization by arranging a atomizing plate having a fuel impingement part between the injection hole of a solenoid fuel injection valve and a nozzle with a plurality of atomizing holes. CONSTITUTION: A valve housing 3 is fitted to the injector body 1 of a solenoid fuel injection valve, and to the forefront end thereof, an injection hole 6 and a curved seat 7 formed in the neighborhood thereof are provided. A valve 5 fitted with a ball 4 intermittently jets fuel by the excitation of a solenoid coil 14. A plurality of atomizing holes 22 are formed in the nozzle 21 arranged before the valve, and a confluent part 27 is formed between the injection hole 6 and atomizing holes 22 and a circular atomizing plate 31 is fixed. The atomizing plate 31 is provided with atomizing holes coinciding with the atomizing holes 22, and a fuel impingement part 34 in the beam part dividing the respective atomizing holes 22. By making the atomizing plate 31 by means of punching working of steel sheet material, the fuel impingement part 34 can be made with high accuracy, so that the atomization can be stabilized and improved.
