The present invention relates to a bead wire which is used for reinforcement of vehicle tires, and a method for producing the same. According to the present invention, through a process by which fine unevenness may be formed on the surface of a wire using electrolytic acid-treatment which allows a drawn wire to pass through an electrolytic bath in which an acid solution is received, and through a chemical displacement plating process by which a plating bath, which contains only one or a compound of two among cobalt, nickel, and manganese, passes through a copper-tin plating solution, a bead wire having superior adhesion is produced, wherein the bead wire has a plating layer formed thereon, the playing layer having a surface roughness of 0.01 to 1.50 µm and comprising: 97 to 99.99 % by weight of copper-tin (Cu-Sn), which consists of 75 to 99.99 % by weight of copper and 0.01 to 25 % by weight of tin; and 0.01 to 3.0% by weight of one or two components from among cobalt (Co), nickel (Ni) and manganese (Mn). |
