<p>PROBLEM TO BE SOLVED: To provide a production method of a flexible tube for an endoscope for which enables the obtaining of the flexible tube for the endoscope excellent in adhesion between a spiral tube and a braid body in a relatively simple production process. SOLUTION: In the production method of the flexible tube 2 for the endoscope, there are arranged a process to make a core material 3 by covering the outer circumference of the spiral tube 31 with a mesh tube 32 formed by braiding a fine line 321, a process to cover the outer circumference near the end part of the core material 3, a process to cover the core material 3, covered with the peeling member 4, with the peeling member 4, a process to remove the skin 5 near the end part of the core material 3 together with the peeling member 4 and a process to braze the spiral tube 31 and the mesh tube 32 near the end part of the core material 3 at a part where the core material 3 is exposed by the removal of the skin 5. A process is preferably arranged before the brazing process to perform a heat treatment of the skin 5 covering the mesh tube 32. The material of the skin 5 preferably contains at least one of a fluororubber and a silicone rubber. The peeling member 4 is preferably formed out of a material containing a fluorine based resin in the area thereof near at least one side thereof.</p> |
