A fuel injector for fuel-injection systems of internal combustion engines has a solenoid coil; a valve needle that is mechanically linked to the solenoid coil and acted upon by a restoring spring in a closing direction, in order to actuate a valve-closure member which, together with a valve-seat face, forms a sealing seat; and a sleeve, which prestresses the restoring spring. The sleeve is integrally formed with a filter element to form a one-part, deep-drawn filter sleeve, which has through-flow openings for filtering the fuel flowing through the fuel injector.
