Abstract
A flexible tube for an endoscope is provided with a spirally-wound tube, a braided tube covering the spirally-wound tube, and a sheath provided on the braided tube. The sheath material is fused and coated on the braided tube to form the sheath. When the sheath material is fused and applied on the braided tube, the sheath material passes through interstices of the braided tube, at the positions facing the clearances between windings, to form a plurality of protruded portions which protruded inward with respect to the braided tube.
