Provided is a fabric artificial blood vessel which has the various properties required of an artificial blood vessel and the same repair function as biological blood vessels according to human recovery capability. When the densities of warp yarns and weft yarns of an outer layer are D1 (number of yarns/25.4 mm ) and D2 (number of yarns/25.4 mm) respectively and the apparent yarn widths of the warp yarns and the weft yarns of the outer layer is W1 (mm) and W2 (mm) respectively the inner layer covering rate C (%) is defined by C = [{(W1—D1+W2—D2) —25.4 W1—W2—D1—D2}/(25.4—25.4)] — 100. The inner layer covering rate C(%)by which an inner layer formed from warp yarns 3 and weft yarns 4 is covered by an outer layer formed from warp yarns 1 and weft yarns 2 is 15% C 75%.
