A fuel injector, in particular an injector for direct injection of fuel into a combustion chamber of a mixture-compressing, spark-ignition internal combustion engine has a solenoid, which cooperates with an armature, and a magnetic internal pole and a magnetic external pole, the armature being connected in a force-locking manner to a valve needle for actuating of the fuel injector, the valve needle having on its injection end a valve-closure member, which cooperates with a valve seat. At least one permanent magnet is arranged in a connecting area between the internal pole and the external pole.
