PROBLEM TO BE SOLVED: To provide a method for manufacturing a catheter tube having improved torque transmissibility and operability while excellent injectability and insertability and the like are maintained. SOLUTION: When a reinforcing layer 6 and an outer layer resin 7 are applied on an inner layer tube 4 made of an excellently lubricated fluoroplastic, the surface of the inner layer tube 4 is previously treated with a defluorinating solution to remove a fluorine component. By doing this, the adhesion force of the reinforcing layer 6 and the outer layer resin 7 are improved for the inner layer tube 4, and the reinforcing layer 6 and the outer layer resin 7 can be prevented from being peeled off. Thus, the torque transmissibility and the operability can be improved while the excellent injectability and the insertability and the like are maintained. |
