PURPOSE:To facilitate manufacture of an electromagnetic fuel injection valve by making it possible to adjust air gap and spring force between the movable iron core and fixed iron core of the valve at the same time and fix a spring stopper, the fixed iron core and a lid body through pressure application/ fastening. CONSTITUTION:A valve housing containing part 20 is formed at one end of combined yoke/main body case 19 and a solenoid coil containing part 25 at the other end while to the valve housing 21 within the containing part 20 a needle valve 22 is attached in such a way as to allow its sliding. The strong magnetic lid body 29 is fitted while the movable iron core fixed to the valve 22 is protroded to the direction of the containing part 25 and a solenoid coil 28 is inserted into the containing part 25. After the combined fuel valve/fixed iron core 34 is inserted, a coil spring 43 is inserted into the fuel channel 32 of the fixed iron core 34 in the state where the two iron cores 24, 34 are pulled back in accordance with proper air gap Xa. A spring stopper 44 and fixed iron core 34 are fixed by pressing and fastening them to the boss part 30 of the lid body 39 from its side by means of a jig 37.
