Abstract
A catheter is configured to reduce a possibility that a shaft of a catheter inserted into a body comes off from a hub on a proximal side when a contrast agent is injected at a high pressure and the shaft is pulled out. The catheter includes a shaft and a hub that are directly fusion-bonded at a shaft accommodation portion of the hub that accommodates a proximal end of the shaft and a vicinity of the proximal end and a minimum inner diameter of the shaft accommodation portion is at any portion of the fusion surface. The shaft is thus prevented from coming off from the hub, safety of a worker is achieved without using an adhesive, a yield is further improved, and a manufacturing cost and a cost required for ensuring safety are reduced.
