Abstract
A catheter having a catheter shaft and a tip. The catheter shaft includes an inner layer, a first reinforcing layer disposed around an outer periphery of the inner layer, an intermediate layer, a second reinforcing layer disposed around an outer periphery of the intermediate layer, and an outer layer that covers the second reinforcing layer. The tip includes a proximal end portion that extends in an axial direction of the catheter and is joined to at least the intermediate layer and the outer layer, between the first reinforcing layer and the second reinforcing layer. The proximal end portion increases the joining strength between the intermediate layer and the tip and the joining strength between the outer layer and the tip. As a result, it is possible to prevent the tip from easily detaching from the catheter shaft.
