Abstract: The invention provides a side 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 made of synthetic resin, a metallic coating layer is formed on the surface of a leg portion except an inverted portion and a coupling head with which a guide flange and a guide post of a slider come into contact. Therefore, no metallic coating layer 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 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.

A recessed groove is defined in the head, thereby providing resilience. The engaging element having the engaging female portion has a tape mounting portion at an end thereof, a vertical fitting face at an inner face of the tape mounting portion, a projecting engaging tongue at a lower portion of the element.
