<p>A zipper component (1) according to the invention includes a metal plating film (3) provided on the surface of a component body (2) made of a metal. Further, in the zipper component (1), at least a part of the component body (2) has been thermally treated before bending and thus the metal plating film (3) has a recrystallized structure wherein at least a part of the metal plating film (3) been recrystallized. Accordingly, since the ductility of the metal plating film (3) can be improved, even when the zipper component (1) is bent, the metal plating film (3) can be deformed to follow the deformation of the component body (2). Therefore, the occurrence of crevicing or cracking in the metal plating film (3) can be prevented.</p> |
