PROBLEM TO BE SOLVED: To provide an endoscope cleaning sheath whose tension strength in the direction parallel to the longitudinal axis is secured.SOLUTION: An endoscope cleaning sheath includes: a multi-lumen tube 21 as a sheath body; a tip side fixed part 22 fixed to the tip of the sheath body; and a base end side fixed part 23 fixed to the base end. The endoscope cleaning sheath includes a linear part, which is a linear part 51 provided with a tip fixed to the tip side fixed part at the tip side connecting position, and a base end fixed to the base end side fixed part at the base end side connecting position, extends along the line core axis between the tip side connecting position and the base end side connecting position, and has a higher tension strength in the direction parallel to the longitudinal axis than the sheath body. |
