SLIDE FASTENER CHAIN AND SLIDE FASTNER

摘要

[Problem] To provide: a flexible slide fastener chain having a small curvature radius and capable of being smoothly bent; and a slide fastener. [Solution] A slide fastener chain (1) is characterized in that: the ratio (Rt) of the sum of a first portion thickness (ta) measured from the upper surface (3c) of an element (3) to the upper surface-side top section (211) of an edge (21) and a second portion thickness (tb) measured from the lower surface (3d) of the element (3) to the lower surface-side top section (212) of the edge (21), to the thickness (t) of the element (3) satisfies the expression (6) described below; and the ratio (Rtl) of the thickness (t) of the element (3) to the overall length (l) of the element (3) satisfies the expression (7) described below. 40%≤Rt (6) 0
