Zusammenfassung:When one end portion of a tubular body is operated, the tubular body shall prevent a deviation of wires, improve a torque transmissibility and pushing force to the other end portion of the tubular body, and improve insertability of a medical device into an interior of the tubular body. Further, the tubular body shall improve flexibility and durability. A tubular body 1 is configured from eight first wires (3a-3h) and eight second wires (5a-5h) twisted into a hollow tubular configuration so that the first wires and second wires are alternately arranged with each other, wherein each of the firstwires (3a-3h) has a substantially circular cross-section, each of the second wires (5a-5h) has recesses in contact portions opposite to adjacent first wires (5ar, 5as, 5br, 5bs, 5cr ...5hs), and hasa convex outer arc (5ap, 5bp etc.) and a convex inner arc (5aq, 5bq etc.) in a cross-sectional view. 本申请提供一种在管状体的一个端部被操作时,能够防止编丝间的偏移、提高向管状体的另一端部的转矩传递性及推进力、并提高其它医疗器件向管状体内部的插入性的管状体,并且,提供一种能够提高柔韧性及耐久性的管状体。所述管状体(1),通过将8条第一编丝(3a~3h
