An electromagnetically actuable fuel injection valve, which serves to supply fuel to mixture-compressing internal combustion engines having externally supplied ignition. The fuel injection valve includes a base plate into which pole pieces having bent poles are inserted. Magnetic coils are fitted onto the pole pieces. A first permanent magnet is inserted between the poles and a second permanent magnet is disposed between the magnetic conductor elements disposed on the other end of the pole pieces. Beginning at the base plate, the magnetic coils and the pole pieces are provided with a sprayed-on plastic jacket. The plastic jacket is inserted together with the base plate into an internal housing bore of a valve housing. A valve group is inserted into an outlet pipe of the valve housing which has an armature oriented toward the poles and joined with a valve needle which on its other end has a closing head that cooperates with a valve seat on a valve seat body and can be raised from the valve seat in the fuel flow direction.
