The object of the present invention is to provide an industrial two-layer fabric which exhibits excellent air permeability with good wear resistance to prevent the wire mark or the hydration mark, while exhibits high rigidity. The present invention includes at least one upper surface side fabric constituted by upper surface side warps and upper surface side wefts, at least one lower surface side fabric constituted by lower surface side warps and lower surface side wefts, and lower surface side warps serving as binding weft yarns, and includes three upper surface side warps arranged to be adjacent to each other in the upper surface side fabric, whereby the upper surface side wefts pass over three consecutive upper surface side warps, and then, pass under one upper surface side warp to pass over another upper surface side warp, and then, passes under three consecutive upper surface side warps.
