PROBLEM TO BE SOLVED: To provide a catheter in which a terminal end of a reinforcement body is fixed without being affected by the physical property of an inner layer of a catheter tube body, and a manufacturing method of the same.SOLUTION: A tube body 100 comprises: a tubular inner layer 110; a reinforcement body 120 arranged on an external surface of the inner layer; and an outer layer 130 arranged so as to cover the external surface of the inner layer and an external surface of the reinforcement body. The tube body has a fastening part 300 for fixing the reinforcement body to the external surface of the inner layer. The fastening part comprises: at least one belt-like body part 310 having both end parts; a fixing part 320 provided in one of both end parts; and a fixed part 330 which is fixed to the fixing part of the body part, and maintains the body part in an annular state in cooperation with the fixing part. The fastening part prevents the reinforcement body from expanding outward in a radial direction of the inner layer while the fixed part is fixed to the fixing part.SELECTED DRAWING: Figure 3 |
