Abstract

In an artificial blood vessel of the present invention, the artificial blood vessel has a warp yarn 1 extending along the axial direction and a weft yarn 2 extending along the circumferential direction of the artificial blood vessel VE, and it has a structure in which the warp yarn 1 extends in a wavy shape when the artificial blood vessel VE is viewed in the radial direction such that positions of the warp yarn 1 at top parts Mt1, Mt2 of a pair of mountain parts M adjacent in the axial direction match in the circumferential direction and a position of the warp yarn 1 at a bottom part Vb of a valley part V between the pair of mountain parts M is offset in the circumferential direction relative to positions of the warp yarn 1 at the top parts Mt1, Mt2 of the pair of mountain parts M.
