Claim:
1. A woven fastener tape for a slide fastener, comprising: an element mount section; and a tape main body section, wherein: the tape main body section includes a plurality of crossing sections in which a bundle of three or more warp yarns cross a bundle of three or more pairs of weft yarns; the tape main body section has a first section with a mesh structure having a plurality of openings between adjacent bundles of the warp yarns and adjacent bundles of the weft yarns; and in the first section, an interlacing density of outermost warp yarns of each crossing section and an interlacing density of outermost pairs of weft yarns of each bundle of each crossing section are respectively higher than an interlacing density of inner warp yarns located between the outermost warp yarns and an interlacing density of an inner pair of weft yarns located between the outermost pairs of weft yarns, wherein each outermost pair of weft yarns includes two adjacent weft yarns and the inner pair of weft yarns includes two adjacent weft yarns, wherein the interlacing density of the outermost warp yarns and the inner warp yarns is based on a number of times the outermost warp yarns and the inner warp yarns interlace with the weft yarns in the crossing section as the outermost warp yarns and the inner warp yarns extend in a longitudinal direction of the fastener tape, and wherein the interlacing density of the outermost pairs of weft yarns and the inner pair of weft yarns is based on a number of times the outermost pairs of weft yarns and the inner pair of weft yarns interlace with the warp yarns in the crossing section as the outermost pairs of weft yarns and the inner pair of weft yarns extend in a width direction of the fastener tape.
