PROBLEM TO BE SOLVED: To provide parison for a balloon that helps stably manufacture a balloon catheter without causing failure to expand, explosion at the moment of expansion, and does not cause an appearance defect such as a split, a crack, a pinhole, a dent or the like on the surface of a balloon even if the balloon is formed, when carrying out biaxial drawing blow molding in the manufacture of a polyamide elastomer balloon. SOLUTION: Parison for a balloon is characterized by 2.9×10<2> MPa or lower and 3.4×10<2> MPa or higher tension elastic modulus. |
