An endoscopic treatment tool (1) has a shaft (2) having a distal end, a proximal end, and a lumen formed along a longitudinal axis； a braid (8) provided between the distal end and the proximal end of the shaft (2)； a distal indicator (11) disposed on the braid (8) ； and a proximal indicator (12) disposed on the braid at a more proximal side of the shaft (2) than the distal indicator； wherein in a state in which the shaft (2) is raised by the raising stand, the distal indicator (11) is positioned in a field of view of the observation optical system when a distal end of the shaft (2) is positioned in a branching region of common bile duct and cystic duct, and the proximal indicator (12) is positioned in a field of view of the observation optical system when a distal end of the shaft (2) is positioned in a branching region of left hepatic duct and right hepatic duct.
