An artificial blood vesselcomprises: an artificial blood vessel bodyand a carbon material filmthat covers the inner wall of the artificial blood vessel bodyThe inner wall which is covered by the carbon material filmis configured so that the water vapor adsorption isotherm shows desorption hysteresis.

Artificial blood vessel

A film formation method is provided with a step for disposing a non-electroconductive long thin tubein a chamberin which the internal pressure thereof is adjustable, generating a plasma inside the long thin tubein a state in which a starting material gas including a hydrocarbon is supplied, and forming a diamond-like carbon film on an inner wall surface of the long thin tube. The long thin tubeis disposed in the chamberin a state in which a discharge electrodeis disposed in one end part of the long thin tubeand the other end part is open. An alternating-current bias is intermittently applied between the discharge electrodeand a counter electrodeprovided so as to be separated from the long thin tube
