Abstract: Fastener elements are attached to a side edge of a fastener tape composed of a knitting structure. An interval between the elements and a wale in the vicinity of the elements is formed into a thin knitted fabric. A flange on a side of a rear mouth of a slider is disposed on the thin knitted fabric and the slider is slid based on this section. For this purpose, an outer side of a bottom end face of the flange is cut out to provide with a notch portion, so that this portion is formed with a small width. Consequently, the thin knitted fabric is slid and introduced securely, and making a pressure contact with a surface of the wale is prevented. Even if a fastener is mounted on trousers and its fabric is pulled in a lateral direction forcibly to open, the elements are prevented from biting into a tape guide groove and escaping.

Therefore, it is possible to obtain a fastener stringer in which no puckering occurs in an element-mounting edge portion even after elements are attached, so that linearity can be secured.
