The present invention provides an artificial blood vessel that can achieve a balance between cell penetration efficiency and crush resistance and can regenerate a blood vessel at very high efficiency. Provided is an artificial blood vessel having a tubular shape, including: a foam containing a bioabsorbable material; a reinforcement A containing a bioabsorbable material; and a reinforcement B including threads containing a bioabsorbable material, the foam being reinforced with the reinforcements A and B, wherein the reinforcement A is a non-woven fabric, a film, or a weft-knitted, warp-knitted, or woven fabric made of knitted or woven fibers, the reinforcement B includes monofilament threads each having a cross-sectional diameter of 0.1 mm or more and 1 mm or less, the reinforcement B includes a winding portion having a helical shape, a ring shape, or an X shape and a warp thread portion stretched in a direction parallel to a longitudinal direction of the artificial blood vessel, and the artificial blood vessel is a composite including the reinforcement A and reinforcement B inside the foam.
