PROBLEM TO BE SOLVED: To thin down a yoke while securing a wide magnetic passage by enabling filling of synthetic resin into a coil housing without providing a cutout part on the flanged yoke integrally formed with a fixed core, in an electromagnetic type fuel injection valve. SOLUTION: In the electromagnetic type fuel injection valve, both ends of a valve housing 2 housing a coil 30 are respectively connected to an outer periphery of the valve housing 2 and the flanged yoke 5a integrated with the fixed core 5 to constitute a valve body 1, the synthetic resin is filled in the coil housing 31, and a coating body 32 covering the valve body 1 and coupler 34 are integrally formed by molding with the synthetic resin. The yoke 5a is formed in a discoid shape to be connected to the coil housing 31 over its entire circumference, the coupler 34 is arranged so as to project to one side of the coil housing 31. The coil hosing 31 is provided with the axial cutout part 31a for pouring the synthetic resin into the coil housing 31 when the coupler 34 and the coating body 32 are formed by molding.
