PROBLEM TO BE SOLVED: To continuously change the stiffness of a catheter shaft along the length direction of the catheter shaft while keeping the profile of the catheter shaft as small as possible and maintaining the crossability and trackability, and to improve pushability and k. A medical balloon catheter with improved ink-resistance is easily provided. A medical balloon catheter having a catheter shaft composed of a distal shaft and a proximal shaft, and having a balloon at a distal end of the distal shaft, wherein the proximal shaft is a single member. The medical balloon catheter is constituted by a member, and a distal end portion of the proximal shaft has lower rigidity than other portions of the proximal shaft. |
