Abstract

A slide fastener configured in such a manner that fastener elements which are connected by connection sections are sewn in a stable attitude to the fastener tapes to increase the strength of attachment between the fastener tapes and the fastener elements. A slide fastener is provided with: a pair of fastener tapes (20); fastener element rows (30) having fastener elements (31) arranged in rows at constant intervals along opposing tape side edges (20a) of the pair of fastener tapes (20); and a slider (40) attached so that the slider (40) can slide along the fastener element rows (30) and can engage and disengage the fastener elements (31) from each other. The fastener elements (31) are connected by connection sections (22) to form the fastener element rows (30), and the fastener elements (31) are attached to the fastener tapes (20) by two or more sewing threads (38) to the surface of the fastener elements (31) so as to be disposed side by side in the widthwise direction of the fastener tapes (20).
