A blood vessel model for medical training not deforming with time and approximated to a real blood vessel without using any other tool when the blood vessel wall of the simulated blood vessel is incised or cut off. The blood vessel model 10 includes a simulated blood vessel 11 simulating a blood vessel and artificially fabricated and a base 12 supporting the simulated blood vessel 11. The simulated blood vessel 11 has a circumferentially exposed part and the other part buried in the base 12. The base 12 has a jointed part 24 disposed in a position below the simulated blood vessel 11 and formed by joining forming edges 26A, 26A of a cutout 26 extending along the simulated blood vessel 11 to impart a tensile stress in the diameter-increasing direction to the simulated blood vessel 11.
