To provide an industrial double layered woven fabric which maintains surface smoothness and a fiber-supporting property and can improve dehydration, air permeability and abrasion resistance that have been problems.

In this industrial double layered woven fabric, the first upper side warps have supplementary portions not passing on the upper side of a part of the upper side wefts to originally pass on the woven fabric structure. In the supplementary portion, the adjacently disposed warp-binding fibers are passed on the upper side wefts in the supplementary portion to form a structure corresponding to the second upper side warp and the second upper side weft on the upper side surface. In the lower side layer, the adjacently disposed lower side warps and warp-binding fibers are cooperated with each other to form two parallel arranged knuckles corresponding to two warps on the lower side of the lower side wefts. The knuckles alternately appear on the lower sides of the lower side wefts to form a ribbed fabric structure group in which two warps are tightly disposed. An interval corresponding to one or more warps is provided between the ribbed fabric structure groups. Vertical grooves extended in the vertical direction between the ribbed fabric structure groups are formed in the lower side layer.
