Claim 7:
8. A method for producing an artificial blood vessel, comprising:
placing a porous artificial blood vessel body in a chamber in which internal pressure is adjustable, and
generating plasma inside the artificial blood vessel body with a raw material gas containing a hydrocarbon supplied, to cover an inner wall of the artificial blood vessel body with a carbonaceous film,
wherein:
the artificial blood vessel body is placed in the chamber with the artificial blood vessel body inserted in a non-conductive outer tube having an inner diameter greater than an outer diameter of the artificial blood vessel body,
a discharge electrode is provided at one end of the outer tube, and the other end of the outer tube is open,
an alternating-current bias is intermittently applied between the discharge electrode, and a counter electrode spaced apart from the outer tube, and
a water vapor adsorption isotherm of the inner wall of the carbonaceous film has desorption hysteresis.
