PROBLEM TO BE SOLVED: To provide a catheter which can be easily manufactured.SOLUTION: A catheter 1 includes: a catheter tube 11 which has an end flexible part 11A including an inner tube (first tube 61) and a plurality of split tube members 620 to 625 that are arranged on an outer circumferential side of the inner tube and are independent from one another; one or more metal rings arranged at the end flexible part 11A; one or more temperature sensors arranged in association with the metal rings; and a handle 12 fitted to a distal end side of the catheter tube 11. A ratio of thickness of the metal ring with respect to an outer diameter of the metal ring is equal to or larger than 7.5%. In the end flexible part 11A, the metal rings and the plurality of split tube members 621 to 625 are each placed around the outer circumferential surface of the inner tube and arrayed in an axial direction of the catheter tube 11.SELECTED DRAWING: Figure 5 |
