TECHNICAL PROBLEMS TO BE SOLVED BY PRESENT INVENTION The object of the present invention is to provide the industrial two-layer fabric which can make papers to be made with a lateral strength higher than that of the fabric constituted by one kind of the conventional upper surface side yarns structure by overcoming the technical difficulty in the adjustment of the fiber orientation due to the complicated factors such as a turbulence generated in the jet stream, the control of the ration J/W, etc. MEANS TO SOLVE TECHNICAL PROBLEMS In the industrial two-layer fabric comprising an upper surface side fabric consisting of upper surface side warps and upper surface side wefts and a lower surface side fabric consisting of lower surface side warps and lower surface side wefts, the upper and lower surface side fabric being bound by foundation binding yarns, all structure portions of the upper surface side warps among a structure constituting said upper surface side fabric are the same, said upper surface side wefts comprises first upper surface side wefts and second upper surface side wefts, structures forming the first upper surface side wefts are different from those forming the second upper surface side wefts.
