[Problem] Provided is a balloon catheter in which a balloon can smoothly deflate even when being pulled. [Means for Resolution] A balloon catheter(10) includes a balloon(100) that can dilate and deflate a hollow-shaped distal shaft(110) that communicates with the balloon and in which an inner shaft(140) is inwardly provided a hollow-shaped intermediate shaft(120) that is connected to a proximal end side of the distal shaft so as to communicate therewith a hollow-shaped proximal shaft (130) 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(150) that is extended 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 (121) in which the intermediate shaft and the proximal shaft overlap each other, a non-fixing portion(123) 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(122) in which the intermediate shaft is fixed to the proximal shaft.
