In a woven slide fastener stringer, a continuous coupling element row is woven successively along a side edge of a fastener tape with a plurality of fixing warp yarns arranged in parallel at the same time when the tape is woven. The fastener stringer is woven with a weaving structure that a tightening force to coupling element portions by at least two of the plurality of the element fixing warp yarns arranged in parallel, which are disposed on a side of coupling heads of the coupling element portions, is smaller than a tightening force to those by at least one of the element fixing warp yarns disposed on a side of connecting portions of the coupling element portions. As a result, the coupling element portions are woven firmly at the side of the connecting portion while gaps between the respective coupling heads can be expanded and reduced slightly. Therefore, the slide fastener stringer can ensure a firm fixing of the coupling element rows and facilitate coupling with the mating coupling element rows. Further, it can stabilize a pitch between the coupling element portions and secure a high density of warp yarns composing each warp yarn pocket. |
