Claim 8:
9. A device for producing an artificial blood vessel, comprising:
a chamber in which internal pressure is adjustable;
a gas supply unit configured to supply a hydrocarbon gas into the chamber;
a discharge electrode and a counter electrode provided in the chamber; and
a power supply unit configured to intermittently apply an alternating-current voltage between the discharge electrode and the counter electrode,
wherein:
the discharge electrode is attached to one end of an outer tube in which the artificial blood vessel body is inserted and discharge is caused to occur with the counter electrode spaced apart from the outer tube so that plasma is generated in the outer tube, to form a carbonaceous film on an inner wall of the artificial blood vessel body, and
a water vapor adsorption isotherm of the inner wall covered by the carbonaceous film has desorption hysteresis.
