Among knitting yams forming stitches of a fastener element attaching portion (11) of a warp knitted tape (10) for a slide fastener composed of multiple wales (W1, W2), a dry heat shrinkage ratio of one or more knitting yams (T1, T2, L1, L2, ST1, ST2,) disposed across adjoining wales (W1 to W5) such that they at least entangle with other knitting yam on the wales (W1, W2) in the fastener element attaching portion (11) is set lower than a dry heat shrinkage ratio of other knitting yams (C1 to C13, T4 to T12, L4 to L10, ST4 to ST10) composing the warp knitted tape (10). Preferably, a multifilament yam composed of fine filament fibers of 0.5 to 4 dTex is used for all the knitting yams. With such a structure, fastener elements can be sewed accurately, so that a soft warp knitted tape having no hardness due to thermal setting and an excellent drape performance can be obtained, this knitted tape allowing a smooth opening/closing operation of a slider after the fastener elements are mounted. <IMAGE>
