PURPOSE: To provide a fastener element covered with a metallic coating layer which is never scraped off by a sliding motion of a slider. CONSTITUTION: A metallic coating layer 20 is formed on the surface of a leg 7 except an engaging head 6 and a turnover part 9 where the guide flange and the guide column of a slider slidingly touching each other in the synthetic resin-made coiled fastener element 1. Hence, as the metallic coating layer 20 is not formed from the beginning in a position where the guide flange and the guide column do not come into sliding contact, the layer 20 is not scaled off and metallic powder is not scattered. Therefore, a fastener element having a beautiful metallic gloss can be used for a long time and an inexpensive and fashionable slide fastener can be obtained. Besides, the fastener element can be applied for a zigzag type, an injection molding type, and a metallic type. |
