PROBLEM TO BE SOLVED: To provide a slide fastener which can show a clear retroreflective phenomenon by providing a retroreflective function on a line of a filament fastener element and its sewing thread. SOLUTION: A retroreflective layer 6 is formed by applying a retroreflective paint on a surface of a line of a filament slide fastener 1 which is formed from an wire which is made of a thermoplastic resin. And a retroreflective phenomenon can be appeared at the line of the filament fastener element 1 and the sewing thread 3 which are observed extremely in the slide fastener easily by applying the retroreflective paint of the surface of the line of filament fastener element 1 with using a synthetic fiber thread as a sewing thread 3 to install a fastener tape 2 on the line of filament fastener element 1 or forming the retroreflective layer 6 by winding the retroreflective film or twisting the film. |
