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 includes a process for applying fluorine coating to an inner surface or a surface that serves as the inner surface. The method is for manufacturing a medical tube having an inner layer composed of one or a plurality of layers, and an outer layer composed of one or a plurality of layers on the outside in a radial direction of the inner layer, which is thicker than the inner layer. It is preferable to apply fluorine coating to a thin member forming the inner layer.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】本発明に係る医療用チューブの製造方法は、内面又は前記内面となる面にフッ素コーティングを施す工程を含む。また、一層又は複数の層により構成された内層と、前記内層より径方向外側に一層又は複数の層により構成され、前記内層よりも厚い外層とを備える医療用チューブの製造方法であって、前記内層を形成する薄肉部材にフッ素コーティングを施すことが好ましい。【選択図】図８
