PROBLEM TO BE SOLVED: To provide a process for producing a tube for medical surgical operation for forming a flexible front end part without increasing a production cost. SOLUTION: An epidural catheter 1 having the flexible front end part 2 is molded by injection molding of a two-layered tube of which the inner layer 11 is stronger than an outer layer 12. The inner layer 11 is removed at a short length at the front end part by machining and the front end part is substantially an end formed near the front end part and a lateral aperture 3 is cut off within the front end part. |
