<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a vitreous carbon-made core tube by which the vitreous carbon-made core tube is manufactured without causing dimensional distortion even in a joined body comprising a cylindrical body and a half-cylindrical body. <P>SOLUTION: The method of manufacturing the vitreous carbon-made core tube includes a step for making the joined body by joining both parallel edges of the half-cylindrical body having a shape formed by halving a cylinder having nearly the same length as that of the cylindrical body and smaller diameter than that of the cylindrical body and formed from the thermosetting resin to the outer surface of the cylindrical body formed from a thermosetting resin so that the axial direction of the cylindrical body is parallel to the axial direction of the half-cylindrical body, a step for carbonizing the joined body and a step for processing to remove a removing part of the cylindrical body which is surrounded by both edges of the half-cylindrical body. <P>COPYRIGHT: (C)2008,JPO&INPIT |
