PROBLEM TO BE SOLVED: To provide a catheter tube having excellent flexibility, pushability, and backup force in bending.SOLUTION: A catheter tube 1 of the present invention includes: a long tubular body (an inner layer 5 and an outer layer 3) composed of a resin; and a rigidity part 7 disposed inside the outer layer 3 along the longitudinal direction and having the rigidity higher than that of the resin. The rigidity part 7 is eccentrically located in the circumferential direction of the tubular body in a cross-section view so as to accurately and promptly deliver the catheter tube to a desired affected area, and also improve the backup force when the catheter tube is bent into a desired shape, which results in a prompt procedure in a manipulation. |
