A fuel injector for fuel-injection systems of internal combustion engines includes a valve-closure element cooperating with a valve seat, and a restoring spring which is situated in a spring pocket opening and acts upon the valve-closure element by a restoring force in the direction of the valve seat. The restoring spring has at least one holding coil in a region of the inflow side, whose area of cross section is positioned perpendicular to an area of cross section of the restoring spring.
