PROBLEM TO BE SOLVED: To provide a surface treatment device and a surface treatment method of a flexible tube which can provide a flexible tube at low cost which is easy to handle, is excellent in terms of hygiene, and is suitable even for medical treatment by modifying a surface of the flexible tube which is adhesive, of which an outer circumferential surface is not slippery, and on which dust is likely to adhere, and provide the surface-treated flexible tube.SOLUTION: A surface treatment device of a flexible tube includes: a guide bar 2 which is inserted into a hollow part of a flexible tube and linearly holds the flexible tube； a guide bar rotation mechanism 3 which rotates the guide bar 2； and a surface treatment tool moving mechanism which moves a surface treatment tool along the flexible tube held by the guide bar 2. The flexible tube is formed by forming a fine rough surface layer on a surface of the flexible tube, forming a lubricant coating layer on a surface of the rough surface layer, and forming a durable coating layer on a surface of the lubricant coating layer by a surface treatment method of the flexible tube using the surface treatment device.SELECTED DRAWING: Figure 2【課題】粘着性を有し、外周面の滑りが悪く、塵埃が付着しやすい可撓性チューブの表面を改質して、取扱いやすく衛生面でも優れ、医療用としても好適な可撓性チューブを廉価に提供できる可撓性チューブの表面処理装置、表面処理方法、及び表面処理した可撓性チューブを提供すること。【解決手段】可撓性チューブの中空部に挿入して該可撓性チューブを直線状に保持するガイドバー２と、該ガイドバー２を回転させるガイドバー回転機構３と、前記ガイドバー２に保持された可撓性チューブに沿って、表面処理具を移動させる表面処理具移動機構とからなる可撓性チューブの表面処理装置と、同表面処理装置を使用した可撓性チューブの表面処理方法により、可撓性チューブの表面に微細な粗面層を、同粗面層表面に潤滑性被膜層を、同潤滑性被膜層の表面に耐久性被膜層を形成されてなる可撓性チューブによる。【選択図】図２
