After elements are mounted, this fastener tape is formed to have a positive pucker condition in which its element attachment edge portion is dented and curved while its tape main body is slightly waved. Consequently, it is possible to construct a woven/knitted fastener stringer capable of securing linearity after this fastener tape is sewed to object clothes.",
