Abstract
A flexible tubular portion for an endoscope having a central axis includes a spiral tube, an outer layer covering the outside of the spiral tube, and an inhibiting portion. The spiral tube includes, along the longitudinal direction of the central axis, a closely wound portion to which an initial tension is applied, and sparsely wound portions provided on the distal side and the proximal side of the closely wound portion. The inhibiting portion inhibits the movement of at least a part of the sparsely wound portions relative to the outer layer in the longitudinal direction of the spiral tube.
