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 having a micro concavo-convex structure on the inner surface includes a process for inserting a bent sheet member or a thin member which is an inner tube into an outer tube, a process for integrating the thin member into the inner surface of the outer tube, and a process for melting at least part of the inner surface of the thin member and exhibiting the micro concavo-convex structure.SELECTED DRAWING: Figure 8【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ことである。【解決手段】細凹凸構造を内面に有する医療用チューブの製造方法であって、外側チューブに、曲げられたシート部材又は内側チューブである薄肉部材を挿入する工程と、前記外側チューブの内面に前記薄肉部材を一体化する工程と、前記薄肉部材の内面の少なくとも一部を溶かし、前記微細凹凸構造を発現させる工程と、を含む。【選択図】図８
