Abstract
For this fastener stringer, at least two stitching lines configured of stitching thread are disposed along the longitudinal direction of a tape on one surface side of the fastener elements. Each of the stitching lines has a stitch at least every two pitches of the fastener elements in the longitudinal direction of the tape and the stitches of each line are disposed so as to deviate from the stitches of the adjacent line, by at least one pitch of the fastener elements in the longitudinal direction of the tape. The fastener stringer thereby has superior fastener element dimensional precision, stitch line abrasion resistance, and flexibility. The multiple stitch lines can be made to look like a tape fabric to be inconspicuous. Moreover, in producing the fastener stringer, a stitching process of the fastener element can be performed efficiently and stably.
