A shaft seal includes a radially outward flange area and a radially inward sealing lip connected to the flange area. An annular spring with a U-shaped or V-shaped cross section is arranged on a radial outer face of the sealing lip, wherein an outer limb bears on the flange area and an inner limb bears on the sealing lip, and wherein a surface of the spring exposed to an exterior of the shaft seal is coated with an elastomer. The invention also relates to a method for producing a shaft seal.
