Abstract
The present invention is a production method for an expansion balloon () for use in a balloon catheter (), including the steps of; forming a balloon tube () by extrusion molding so as to have a cross section orthogonal to an axial direction with the shape of a circle on the outside and the shape of a polygon having a circumcircle on the inside; and placing the balloon tube () in a mold to perform biaxially-stretched blow molding to obtain the balloon, whereby it is possible to produce the expansion balloon () that has no unevenness in film thickness of a straight pipe part () and allows stable folding control by simple processes with favorable molding yields.
