In a balloon tube () which is processed after it is mounted on a mold, a bag part () has a plurality of parts having a different drawability in a radial direction centered around an axial direction X, disposed along the axial direction X. The highest drawability part (), which has the highest drawability, is disposed to separate from both ends of the bag part () in the axial direction X thereof. The balloon tube () is preferable to stably fabricate a balloon having a uniform film thickness.

Balloon tube, balloon, balloon catheter, and balloon tube fabrication method

A resin roller () is produced by disposing a core body () in a forming metal mold () having a cylindrical metal mold () and core supporting members () furnished at both edge parts of the cylindrical metal mold () as well as causing the core supporting members () to hold said both edge parts, and pouring a forming resin into the metal mold and solidifying it. The resin roller () has the core body () of the same outer diameter over a full length and a cylindrical resin-formed body (), sealing members () are furnished around the core body () in the vicinity of both edge parts of the resin-formed body (), and the core body () is disposed such that the sealing members () contact edge faces () at sides of a roller forming space of the core supporting members ().
