An industrial two-layer fabric which comprises eight pairs of warps obtained by arranging eight upper surface side warps and eight lower surface side warps, and a plurality of upper surface side wefts and lower surface side wefts, and has an upper surface side layer and a lower surface side layer bound with warp-direction yarns. In the lower surface side layer, warps are formed by successively arranging a design in which one warp passes over four successive lower surface side wefts, passes under one lower surface side weft, passes over two lower surface side wefts, and passes under one lower surface side weft while shifting the design by three lower surface side wefts, and two adjacent lower surface side warps simultaneously weave therein, from the lower surface side, one lower surface side weft.
