Abstract
A curved slide fastener in which a convex element attaching edge portion which is curved convexly and outwardly and a concave element attaching edge portion which is curved concavely and inwardly are arranged to face each other on opposing side edges of a pair of fastener tapes, a stretchable member which is elastically deformed so as to be stretchable in a length direction of the fastener tape is attached to an edge side of the fastener tape on an opposite side to the convex element attaching edge portion, and the stretchable member is fixed to the fastener tape in a contracted state and maintains a foundation structure of the fastener tape in a contracted state, thereby preventing occurrence of wrinkle or swelling on the tape surface.
