Slide fastener joined to flexible material

A fastener stringer comprising:

• a fastener tape having first and second side-edge portions extending along a lengthwise direction;
• and
• a fastener element arranged onto the fastener tape,
• the fastener tape configured by a plurality of warp threads and at least one weft thread, each warp thread extending in the lengthwise direction, the weft thread extending in a crosswise direction that is orthogonal to the lengthwise direction, and each warp thread extending to repeat crossing over the weft thread at a tape top surface side and crossing over the weft thread at a tape bottom surface side, the fastener tape comprising:
• a first tape region in which first portions of the weft thread are arranged at a first pitch interval, the first portion being a portion crossed by the warp threads;
• a second tape region in which second portions of the weft thread are arranged at a second pitch interval, the second portion being crossed by the warp threads and the second pitch interval being same as the first pitch interval;
• and
• a third tape region positioned between the first tape region and the second tape region and including third portions of the weft thread arranged at third pitch interval that is equal to the first or second pitch intervals, the third portion extending between the first and second portions of the weft thread and none of the warp threads are provided in the third tape region, wherein
• the first tape region is positioned closer to the first side-edge portion than the second side-edge portion, the second tape region is positioned closer to the second side-edge portion than the first side-edge portion, the third tape region is positioned closer to the second side-edge portion than the first side-edge portion, and the fastener element is arranged onto the first tape region and onto the first side-edge portion, wherein
• the first tape region includes a first sub tape region adjacently arranged to the third tape region and a second sub tape region arranged closer to the first side-edge portion than the first sub tape region, and wherein a structure of the first sub tape region differs from a structure of the second sub tape region.
