An industrial two-layer fabric comprising: an upper side fabric comprising upper side warps and upper side wefts; and a lower side fabric comprising lower side warps and lower side wefts; wherein the upper side warps comprises a first warp set that contains two of the upper side warps and a second warp set that contains one of the upper side warps and one of the lower side warps placed below the one of the upper side warps; the first warp set and the second warp set are placed alternately; at least one of the upper side warps of the first warp set functions as a warp binding yarn that binds the upper side fabric and the lower side fabric; wherein, at a position where two adjacent lower side warps of adjacent second warp sets pass under one of the lower side wefts, the warp binding yarn placed between the two adjacent lower side warps passes under the one of the lower side wefts; and wherein the two adjacent lower side warps and the warp binding yarn pass over two lower side wefts adjacent to the one of the lower side wefts.
