A fuel injector valve comprises a magnetic spherical valve member, a non-magnetic valve seat member on which the spherical valve member is seatable, a main magnetic pole member disposed opposite to the valve seat to attract the spherical valve member, a side magnetic pole member located spaced apart from and between the extreme end of the main magnetic pole member and the extreme end of the valve seat member, and a fuel injection section through which fuel passing through the clearance between the valve seat member and the spherical valve member is injected out of the fuel injector valve, so that the fuel injector valve is improved in response characteristics, stability and durability to provide the injector valve suitable for a so-called single point fuel injection system.
