The outer tube 2 includes a superelastic or pseudoelastic metal tube 2b and a synthetic resin tube 2a covering the metal tube, the metal tube 2b having a distal zone provided with a slit or perforations 2e so that the distal zone is more flexible and deformable than the remainder of the metal tube. Also provided is a catheter 100 comprising a main body section which includes a superelastic metal tube 101 and a synthetic resin layer 104 covering the metal tube, the metal tube 101 having a distal zone provided with a slit or perforations 106 so that the distal zone is more flexible and deformable than the remainder of the metal tube.
