(54) Slide fastener


(57) The invention provides a slide fastener comprising a fastener element in which a metallic coating layer is formed, the metallic coating layer being never scraped by a sliding of a slider. In a coil-shaped fastener element (1) made of synthetic resin, a metallic coating layer (20) is formed on the surface of a leg portion (7) except an inverted portion (9) and a coupling head (6) with which a guide flange and a guide post of a slider come into contact. Therefore, no metallic coating layer (20) is formed on a portion with which the guide flange and guide post of the slider come into contact. As a result, such an event that the metallic coating layer (20) is scraped and that metallic powder is scattered is prevented, so that a fastener element having a beautiful metallic gloss can be used for a long term and a cheap, fashionable slide fastener is obtained. This invention can be applied to zigzag type, injection molded type and metal type fastener elements.
