The invention provides an endoscope treatment tool which can simultaneously improve the rotary operability and movability of a moveable distal end portion so as to seek to simplify the operations of hands. The endoscope treatment tool includes: the moveable distal end (5) for the treatment of an organism a first coil sheath (6) including flexibility which is composed by a single element wire (6a) being spirally wound a second coil sheath (7) including flexibility which is composed by a plurality of element wires (7a) being spirally wound in the same direction, and is coaxially mounted outside of the first coil sheath (6) with the first coil sheath (6) or internally mounted in the first coil sheath (6) an operating wire (8) including flexibility which are shaped to extend in a long and thin manner, the distal end of the operating wire is connected to the movable distal end portion (5) the operating wire passes through the first coil sheath (6) and can move corresponding to the first coil sheath (6), for performs the extending and retracting operation of the operating wire (8) the distal end of the second coil sheath (7) is fixed to the movable distal end portion (5), and the base end of the second coil sheath (7) is fixed to the operating portion.
