To provide a bilayer woven fabric for industry, having a lower surface structure excellent in drainage, fiber-supporting property, rigidity and abrasion resistance.

In the bilayer woven fabric for industry, in which an upper layer woven fabric is bound to a lower layer woven fabric, the lower surface side weft has a structure in which the weft is passed through the upper side of one lower surface warp and then, passed through the lower side of one lower surface side warp and passed through the upper side of one lower surface side warp and then, passed through the lower side of continuing five lower surface side warps, and the lower surface warp has a structure in which the warp is passed through the upper side of continuing four lower surface side wefts and passed through the lower side of one lower surface side weft and passed through the upper side of continuing three lower surface side wefts and passed through the lower side of one lower side weft and passed through the upper side of continuing two lower surface side wefts and passed through the lower side of one lower surface side weft and passed through the upper side of continuing three lower surface side wefts and passed through the lower side of one lower surface side weft.
