A press-machined fuel induction pipe 40, a hollow tubular type of fixed core 1 with a flange at its upper end, and a nozzle holder 18 that was press-machined into a slender tubular shape and has an orifice plate equipped with a valve seat at the lower end of the nozzle holder, are connected by welding. The upper inner surface of nozzle holder 18 and the outer surface of fixed core 1 are welded after being press-fit. A movable core 14 and a valve body 16 are connected to the welded assembly via a point 15 having a spring function. On the outer surface of nozzle holder 18 is provided an electromagnetic coil 2, the outside of which is provided with a tubular yoke 4 whose upper end is connected by welding to the flange 1a of fixed core 1 and whose lower end is press-fit on the outer surface of nozzle holder 18.
