PROBLEM TO BE SOLVED: To provide a method for manufacturing a medical tube to which a biological material or medical liquid is less likely to adhere.SOLUTION: A method for manufacturing a medical tube is a method for manufacturing a medical tube having an inner peripheral surface in which a micro concavo-convex structure is formed, and includes a process for winding a sheet-like first mold having a micro concavo-convex pattern on its surface around a core pin so that the surface is an outer surface, a process for inserting the core pin around which the first mold is wound into an internal space of a second mold so that a gap is formed between the core pin and an inner surface of the second mold, a process for putting a molding material in the gap to mold the tube, a process for drawing out the core pin, and a process for peeling off the first mold from the tube.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2017,JPO&INPIT【課題】生物学的物質又は医療用液体が付着しにくい医療用チューブの製造方法を提供する。【解決手段】本発明に係る医療用チューブの製造方法は、微細凹凸構造が形成された内周面を有する医療用チューブの製造方法であって、微細凹凸パターンを表面に有するシート状の第1の金型を前記表面が外面になるようにコアピンに巻回する工程と、第2の金型の内部空間に、前記第2の金型の内面との間に間隙が形成されるように、前記第1の金型を巻回した前記コアピンを挿入する工程と、前記間隙に成形材料を充填してチューブを成形する工程と、前記コアピンを引き抜く工程と、前記第1の金型を前記チューブから剥がす工程と、を含む。【選択図】図8
