The present invention relates to a tubular woven fabric useful as a transport hose for a fluid or a powder, as a protective hose for linear bodies such as wires, cables and conduits, as a tubular filter, or as a base material of a vascular prosthesis. The tubular woven fabric comprises warp yarns and weft yarns interwoven with each other, the tubular woven fabric having an outer diameter with a variation of within 10% along the warp direction and satisfying the following formula:whereinL1 is a gauge length of the tubular woven fabric when compressed in the warp direction by applying a stress of 0.01 cN/dtex, as determined after the outer diameter of the tubular woven fabric is measured without applying stress to the tubular woven fabric to determine a maximum outer diameter and then gauge marks are drawn around an outer circumference of the tubular woven fabric so that the gauge marks are separated by a length of five times the maximum outer diameter of the tubular woven fabric; andL2 is a gauge length of the tubular woven fabric when elongated in the warp direction by applying a stress of 0.01 cN/dtex, as determined after the outer diameter of the tubular woven fabric is measured without applying stress to the tubular woven fabric to determine a maximum outer diameter and then gauge marks are drawn around an outer circumference of the tubular woven fabric so that the gauge marks are separated by a length of five times the maximum outer diameter of the tubular woven fabric.
