An electromagnetic fuel injection valve that intermittently injects fuel, and when the valve is retracted, the flange portion comes into contact with a stopper provided at the rear end of the valve seat to regulate the retracted position of the valve. An electromagnetic fuel injection valve characterized by being made of a porous sintered material having fine voids on its surface.
