PURPOSE: To achieve a rationalization of manufacture by shortening a production process of sutures comprising a plurality of pressing processes to reduce equipment.

CONSTITUTION: A linear unbroken metal wire is fed spacing to perform a squeezing of the axis parts thereof and a boring of a suture insertion hole 12. Then, a V-shaped notch molding and a sized cutting of the metal wire are performed simultaneously with the same pressing die at the final stage and then, a V-shaped cut 13 is made at the tip of the needle cut being sized as guide rim for the suture.
