Woven Fastener Stringer and Slide Fastener

A woven fastener stringer including:

• a woven fastener tape having a tape main body and an element attaching portion placed along one side edge of the tape main body;
• and
• a continuous element row woven into and fixed to the element attaching portion along a length direction of a tape simultaneously when the fastener tape is woven, in which
• each fastener element configuring the continuous element row is woven such that an engaging head portion of the fastener element projects outward from a tape side edge of the fastener tape,
• the element attaching portion includes a weft thread which is continuously weft-inserted from the tape main body, an upper fixing warp thread and a lower fixing warp thread which run in a warp direction on an upper surface of an upper leg and on a lower surface of a lower leg of the fastener element, and fastening warp threads which run in the warp direction while alternately straddling the upper leg and the lower leg in the continuous element row, and
• the weft thread is folded back by converting a running direction while interlacing with a upper direction converting portion configured by at least the one upper fixing warp thread and a lower direction converting portion configured by at least the one lower fixing warp thread at a location close to the engaging head portion wherein
• an upper extension portion configured by at least the one upper fixing warp thread is placed in adjacent to the tape main body side of the upper direction converting portion, and a lower extension portion configured by at least the one lower fixing warp thread is placed in adjacent to the tape main body side of the lower direction converting portion.
