Claim:
1. A balloon catheter having multiple tubular members, an adapter member connected thereto, a balloon for dilation of a constricted blood vessel, and a resin film on an outer surface of the balloon catheter, characterized in that a peeling strength of balloon surfaces when surfaces of the balloon adhere to each other in a state when the balloon is wrapped around at least one of the tubular members is 0.06 N or more and 1.00 N or less, and the modulus of the balloon in the axial direction is 100 N/mm 2 or more and 250 N/mm 2 or less, wherein the peeling strength is maximum strength as determined while two balloon samples having their outer surfaces facing each other and adhering to each other, and one of the balloon samples is pulled in a direction perpendicular to the other balloon sample in a tensile strength tester, wherein the resin film has a layer of a urethane-base polymer consisting of:
