摘要： Provided is a copper alloy fastener element which improves season cracking resistance by a means different from that of increasing a ratio of a β phase. The copper alloy fastener element includes a copper-zinc alloy as a base material, the base material having: an apparent zinc content of from 34 to 38%; a dendrite structure; and a β phase at a ratio of 10% or less.

摘要： A slide fastener includes a pair of left and right fastener tapes; and a pair of element rows including a plurality of fastener elements that face edge portions of the fastener tapes on sides facing each other along a length direction of the fastener tapes, and to which a slider that engages with the pair of element rows is slidably attached. The fastener element is made of a metal, a water-repellent layer made of a water-repellent agent is provided on the fastener tape, and adhesion of water to the fastener tape is prevented by the water-repellent layer.
