PROBLEM TO BE SOLVED: To improve the rust resistance of a ferritic stainless steel wire which has been inferior by controlling and prescribing its surface properties without changing the components therein, so as to secure stable rust resistance, thus to remarkably improve the applying ratio of the ferritic stainless steel wire to markets. SOLUTION: The ferritic stainless steel wire having excellent rust resistance has a composition comprising, by weight, 0.05 to 3.0% Si, 0.1 to 2.0% Mn,≤0.04% P,≤0.01% S, 14.0 to 24.0% Cr and 0.005 to 0.15% C+N, and the balance Fe with inevitable impurities. Regarding the surface roughness in the longitudinal direction of the steel wire, Rmax is controlled to≤10μm or Ra is controlled to≤1.0μm. If required, the 0.2% proof stress of the steel wire is controlled to≥350 N/mm<SP>2</SP>, or the steel wire is subjected to bright annealing, and has a wire diameter of≤4 mm.
