Abstract
A fastener stringer has a fastener tape provided with a tape main body portion and an element attaching portion and a plurality of fastener elements fixed by weaving to the element attaching portion of the fastener tape at the same time of weaving of the fastener tape, and is provided with a weaving structure with one pitch per one-rotation. A weft yarn of the fastener tape has a fineness larger than that of at least a part of a warp yarns disposed in the tape main body portion. Thereby, the productivity of the fastener stringer can be increased to reduce the cost. Further, the density of the weft yarn in the fastener tape can be increased, and the fastener tape can be less likely to be misaligned.
