PURPOSE: A tape for a slide fastener is provided to obtain a beautiful sewed product regardless of which the sewed product is hard or soft. CONSTITUTION: At least some parts of constituent yarns are extended in a warp direction outside and adjacent a core thread woven or knitted in an element attachment edge portion(4). The yarns have a higher elongation recovery ratio than all the other constituent yarn(6c to 6n) and the core threads extending in the warp direction. The elongation recovery ratio is expressed by the following equation. R={(L1-L2)/(L1-L0)}*100, wherein L0 is an original length of yarn, L1 is a length of yarn when pulled under a predetermined tension, and L2 is a length of yarn after formed to have a positive pucker condition.
