Abstract The present invention intends to provide a knitted-in slide fastener. A basic structure of knitting of a fastener element attaching portion (T1) formed along a side edge of a fastener tape is formed of chain knitting yarns (5 – 8) and weft in-laid yarns (10, 11). A fastener element row (ER) is disposed on an upper face of sinker loops of binding chain knitting yarns (6, 7), attaching portion foundation chain knitting yarns (5, 8) and the weft in-laid yarns (10, 11) and a leg portion (L) of each element portion (E) is tightened and bound by needle loops of the binding chain knitting yarns (6, 7) from an upper face thereof. The weft in-laid yarns (11) inserted such that they are inverted alternately between two rows of wales (W1, W2) disposed in the element attaching portion (T1) beside the tape main portion have a size larger than other weft yarns. The weft in-laid yarns (10) inserted such that they are inverted alternately between the wale (W1) disposed in the element attaching portion (T1) nearest to the tape main portion (T) and wales (W2, W3) formed by any one of the binding chain knitting yarns (6, 7) have heat shrinkage characteristic.
