A fuel injector for fuel-injection systems of internal combustion engines includes a valve needle cooperating with a valve-seat surface to form a sealing seat, and an armature engaging with the valve needle, the armature being axially moveable at the valve needle and being damped, via a damping element, which is located in a recess in a downstream-side end face of the armature, with respect to a cup-shaped sleeve positioned downstream from the armature and joined to the valve needle in force-locking manner. Furthermore, the fuel injector includes a filter element, the filter element being positioned downstream from the armature in the cup-shaped sleeve.
