PURPOSE: To provide a manufacturing method of a wire wherein the exchange frequency of a capillary can be reduced by increasing the number of times of bonding until abnormality generation due reverse deformation when a loop is formed. CONSTITUTION: A surface layer eliminating treatment is performed on an intermediate yarn stock obtained by plastic-working an ingot. After a wire is formed by stretching the yarn stock, final annealing and post-treatment of wire lubricant coating are performed. Thereby adhesion of the wire lubricant is increased, troubles causing loop abnormality are hardly generated, and the capillary exchange frequency is reduced. |
