Fabric for binding tape, and binding tape

The invention provides a binding tape 10 and a fabric for the binding tape 10. The binding tape 10 includes a base material 11 and an adhesive layer 12 that is made on a back side of the base material 11 which contacts an outer peripheral surface of the wire bundle W. The base material 11 is made up of a single sheet of fabric 20. The fabric 20 is made of knitted fabric that is knitted by use of warp yarn 21 and weft yarn 22, both of which are made from polyester fibers, by means of a warp-knitting weft insertion method. A thickness of the warp yarn 21 is 22 to 56 decitexes; a thickness of the weft yarn 22 is 440 decitexes or more; and a density of the warp yarn 21 is 10 to 30 wales/inch.
