<p>A first linear member (51) made of a first resin material having a relatively high rigidity is wound in a dense spiral in a first region (221) and in a sparse spiral in a second region (223) of a base tube (4) for a catheter (1), and a second linear member (52) made of a second resin material having a relatively low rigidity is wound in a sparse spiral in the first region (221) and in a dense spiral in the second region (223) of the base tube (4). Then, the first linear member (51) and the second linear member (52) are melted by heating, followed by solidifying the molten materials, thereby forming a catheter (1) excellent in pushability, torque transmitting capability, following capability, kink resistance and safety. <IMAGE></p> |
