PROBLEM TO BE SOLVED: To provide a wire element superior in corrosion resistance for reinforcing rubber; the wire element for reinforcing the rubber, which has adequate adhesive properties to the rubber in addition to the corrosion resistance; and a rubber composite consisting of the rubber and the wire element for reinforcing the rubber. SOLUTION: The wire element for reinforcing the rubber superior in the corrosion resistance has a coating layer containing Cu and Zn on the surface of a steel strand, wherein the coating layer has such thickness that the total circumferential length of the steel strand in a circumferential region having the thickness of 0.1μm or more is 50% or more with respect to the total circumferential length of the steel strand, when a cross section perpendicular to the longitudinal direction of the wire element is observed; and in the above circumferential region, contains (1) 50 to 95 mass% Cu by average in a region from the outermost surface of the coating layer to a 0.01μm deep position, in a depth direction, and contains (2) 60 mass% or more Zn by average in a region from a 0.1μm deep position from the outermost surface of the coating layer to the surface of the steel strand, in a depth direction.
