Abstract
A catheter includes a hollow shaft having a tip part decreasing in diameter in a direction of a distal end, and a coil body covering the hollow shaft. The tip part has a small diameter portion, a large diameter portion, and a tapered portion gradually increasing in diameter from the small diameter portion toward the large diameter portion. The coil body has a substantially cylindrical joint part at which an end portion of the coil body in the direction of the distal end is joined in the circumferential direction. The joint part is located over the tapered portion and/or the small diameter portion, and in a state in which the hollow shaft extends substantially linearly, the distance between an inner peripheral surface of the joint part and outer peripheral surfaces of the tapered portion and/or the small diameter portion increases in the direction of the distal end.
