To provide a wire-drawing method that is advantageous for obtaining a steel wire of high strength and high ductility from high-strength steel wire typified by the high-carbon steel wire.

Steel wires of ≥0.60 wt.% carbon content are subjected to the multistage wet wire drawing process to produce steel wires of ≤0.40 mm diameter. In this case, the dices having the peripheral walls made of single crystal diamond chips or sintered diamond particles with a particle size of ≥10 μm are used at least at the final step of the multistage wet wire drawing.
