関の電磁式燃料噴射弁。 A valve element that floats and faces a valve seat attached to the holder is supported at approximately the center of a leaf spring whose peripheral edge is supported by a holder, and the elastic force of the spring acting on the valve element supports the valve element that floats and faces the valve seat attached to the holder. The leaf spring is bent to seat the valve body on the valve seat to close the valve, while the valve body is lifted by a predetermined amount by the electromagnetic attraction force of the valve opening coil to open the valve, and the valve body and valve seat are brought into contact with each other. In an electromagnetic fuel injection valve for an internal combustion engine that allows fuel to flow through a gap, the outer peripheral edge surface of a flat movable element fixed to the outer periphery of the valve body and the outer peripheral edge surface are connected to each other when the valve opening coil is energized. An electromagnetic fuel injection valve for an internal combustion engine, characterized in that a foil layer made of a non-magnetic material is provided on at least one surface of the housing end face made of a magnetic material to be attracted.
