Zusammenfassung:	To provide an artificial blood vessel hardly dilating even when being used on a part having a heavy load such as artery.SOLUTION: In an artificial blood vessel which is a tube artificial blood vessel formed by enhancing a porous sponge layer with a nonwoven fabric layer and a mesh layer, the sponge layer, the nonwoven fabric layer and the mesh layer are laminated in this order from the center side of the artificial blood vessel, the sponge layer and the nonwoven fabric layer comprise a bioabsorbable material, the nonwoven fabric layer has a fiber diameter of 0.5 μm or more and 10 μm or less, and the mesh layer comprises mesh comprising heat-treated polyvinylidene fluoride.SELECTED DRAWING: None 【課題】本発明は、動脈等の負荷が大きい部位に用いた場合であっても拡張が起き難い人工血管を提供する。【解決手段】多孔質のスポンジ層を不織布層及びメッシュ層で強化したチューブ状の人工血管であって、前記スポンジ層、前記不織布層及び前記メッシュ層は前記人工血管の中心側からこの順番で積層しており、前記スポンジ層及び前記不織布層は生体吸収性材料からなり、前記不織布層は繊維径が０．５μｍ以上１０μｍ以下であり、前記メッシュ層は加熱処理されたポリフッ化ビニリデンからなるメッシュからなる人工血管。【選択図】なし
