ABSTRACT:
A tubular object manufacturing method comprising the steps of applying liquid heat-resistant resin containing an inorganic filler as desired onto an outer surface or inner surface of a core member which is a shaping mold to thereby form a coating layer, solidifying or hardening the applied liquid heat-resistant resin until the coating layer becomes strong enough to maintain at least a structure of the tubular object, and taking the tubular object out from the core member. In the method, liquid heat-resistant resin with a viscosity of 10 to 15000 poise at 25.degree. C. is continuously fed by means of a dispenser onto the outer surface or inner surface of the core member while rotating the core member, and a feeder part of the dispenser is moved in the direction of a rotation axis of the core member so that the fed liquid heat-resistant resin is helically wound to thereby form the coating layer. Tubular objects obtained by the manufacturing method is excellent in thickness precision, less in resin loss, and capable of being given desired thickness distribution in the axial direction as necessary.
