An industrial two-layered fabric with a complete structure, including: a fabric on a front surface side consisting of a weft on the front surface side and a warp on the front surface side; a fabric on a back surface side consisting of a weft on the back surface side and a warp on the back surface side, the fabric on a front surface side and the fabric on a back surface side are bound by a binding warp; first pairs (1, 4) of warps consisting of a warp on the front surface side that weaves only the weft on the front surface side and a warp on the back surface side that weaves only the weft on the back surface side; and second pairs (2, 3) of warps consisting of a binding warp on the front surface side and a binding warp on the back surface side, which functions to bind the fabric on the front surface side and the fabric on the back surface side, wherein the one of the binding warp constituting each one of the second pairs (2, 3) of the warps consecutively forms a plurality of knuckles on the fabric on the front surface side, while the other of the binding warps does not emerge on the front surface side at a portion where a plurality of knuckles are formed by the one of the binding warp, and the other binding warp consecutively forms a plurality of knuckles on the fabric on the front surface side, while the one binding warp does not emerge on the front surface side at a portion where a plurality of knuckles are formed by the other of the binding warp, whereby a complementary structure is formed, wherein two adjacent ones of the second pairs (2, 3) of warps are arranged between two of the first pairs (1, 4) of warps, wherein each of the two second pairs (2, 3) of warps is arranged to be adjacent to one of the first pairs (1, 4) of warps, and such an arrangement is repeated, wherein the binding warp on the back surface side among the second pairs (2, 3) of the warps passes below the wefts on the back surface side, wherein the diameter of the warp that weaves only the weft on the front surface side is set to be substantially the same as the diameter of the binding warp, and wherein the diameter of the warp that weaves only the weft on the back surface side is set to be larger than the diameter of the binding warp. a fabric on a back surface side consisting of a weft on the back surface side and a warp on the back surface side, the fabric on a front surface side and the fabric on a back surface side are bound by a binding warp; first pairs (1, 4) of warps consisting of a warp on the front surface side that weaves only the weft on the front surface side and a warp on the back surface side that weaves only the weft on the back surface side; and second pairs (2, 3) of warps consisting of a binding warp on the front surface side and a binding warp on the back surface side, which functions to bind the fabric on the front surface side and the fabric on the back surface side, wherein the one of the binding warp constituting each one of the second pairs (2, 3) of the warps consecutively forms a plurality of knuckles on the fabric on the front surface side, while the other of the binding warps does not emerge on the front surface side at a portion where a plurality of knuckles are formed by the one of the binding warp, and the other binding warp consecutively forms a plurality of knuckles on the fabric on the front surface side, while the one binding warp does not emerge on the front surface side at a portion where a plurality of knuckles are formed by the other of the binding warp, whereby a complementary structure is formed, wherein two adjacent ones of the second pairs (2, 3) of warps are arranged between two of the first pairs (1, 4) of warps, wherein each of the two second pairs (2, 3) of warps is arranged to be adjacent to one of the first pairs (1, 4) of warps, and such an arrangement is repeated, wherein the binding warp on the back surface side among the second pairs (2, 3) of the warps passes below the wefts on the back surface side, wherein the diameter of the warp that weaves only the weft on the front surface side is set to be substantially the same as the diameter of the binding warp, and wherein the diameter of the warp that weaves only the weft on the back surface side is set to be larger than the diameter of the binding warp.
