Provided is a balloon catheter in which a balloon can smoothly deflate even when being pulled. A balloon catheter includes a balloon that can inflate and deflate, a hollow distal shaft that communicates with the balloon and in which an inner shaft is inwardly provided, a hollow intermediate shaft that is connected to a proximal end side of the distal shaft so as to communicate therewith, a hollow proximal shaft that overlaps a proximal end side of the intermediate shaft so as to be connected thereto and that communicates with the intermediate shaft, and a reinforcement body that extends from the proximal shaft to the distal shaft and is fixed to the proximal shaft, in which the intermediate shaft is more flexible than the distal shaft, and in an overlapped portion in which the intermediate shaft and the proximal shaft overlap each other, a non-fixing portion in which the intermediate shaft and the proximal shaft overlap each other without being fixed extends to a distal end side relative to a fixing portion in which the intermediate shaft is fixed to the proximal shaft. |
