A knitted fastener stringer comprising a fastener tape of a warp knit structure in which an element attaching portion is disposed along one side edge of a tape main body portion, and a continuous fastener element which is knitted and fixed to the element attaching portion, the element attaching portion being configured by at least a fixing chain stitch yarn which holds and fixes pairs of upper and lower leg portions of the fastener element in a tape front and rear direction, the fixing chain stitch yarn comprising a double structure with first needle loops which are knitted into a ground structure on a lower surface side of the pairs of the upper and lower leg portions of the element attaching portion and second needle loops which are disposed on an upper surface side of the upper and lower leg portions, and fasten and fix the upper and lower leg portions,

• wherein one of the first needle loops and one of the second needle loops of the fixing chain stitch yarn are formed at each one pitch of the fastener element, the first needle loops interlace with corresponding needle loops of ground knitting yarns and subsequent first needle loops, and each second needle loop fastens and fixes the upper and lower leg portions to the element attaching portion by striding across them while interlacing with subsequent second needle loops in series.
