    Abstract: PROBLEM TO BE SOLVED: To provide a method for making a steel wire high in strength while keeping a satisfactory ductility. SOLUTION: A high carbon steel wire rod having 0.85-1.10 mass% carbon content is subjected to a front-step wire-drawing under a prescribed wire-drawing rate. An intermediate wire rod subjected to the front-step wire-drawing is subjected to a patenting treatment for adjusting the tensile strength within the range of 1,323-1,666 MPa, and then is subjected to a latter-step wire-drawing containing the last wire-drawing.
