To provide a method for the manufacture of a nerve regeneration-inducing tube being excellent in pressure resistance, shape recovery property, anti-kink property, film exfoliation resistance, property of prevention of invasion of outer tissues and leakage resistance. The present invention is a method for the manufacture of a nerve regeneration-inducting tube in which the outer surface of the tubular body knitted with a plurality of ultrafine fibers comprising biodegradable polymer is coated by application of a collagen solution for plural times to coat and then collagen is filled in the inner area of the above tubular body, characterized in that , viscosity of the collagen solution which is firstly applied on the outer surface of the tubular body is made 2 cps to 800 cps or, preferably, 5 cps to 200 cps. Preferably, viscosity of a collagen solution to be applied later is made high as compared with that of the firstly-applied one. |
