Abstract: The channel tube for endoscope according to the present invention is provided with: an inner-layer tube inside which a through hole extending in a longitudinal direction is formed, the inner-layer tube having as a base material thereof an elastomer or a flexible resin; an elastomer layer comprising a polymer elastomer, the elastomer layer being disposed so as to cover the outside of the inner-layer tube, and the surface of the elastomer layer being exposed to the outside; a reinforcing layer part including a flexible reinforcing member, the reinforcing layer part being disposed so as to surround the inner-layer tube; and a buffer layer part which deforms more readily than the reinforcing layer part, the buffer layer part being layered on the reinforcing layer part and disposed between the inner-layer tube and an outer peripheral surface of the elastomer layer.
