There is provided an endoscope that allows the distal end portion of a wire and a treatment tool-elevator to be easily connected to each other. An engaging portion (100) is provided at the distal end portion of a wire (60). An elevator (30) is provided with a contact portion (101) that applies a rotational moving force acting in a fallen direction to the elevator (30) in a case where the engaging portion (100) is in contact with the contact portion. The elevator (30) is provided with a housing portion (102) in which an opening (104) is formed. A wall portion (81) is provided at a position that faces the movement trajectory of the engaging portion (100) in a case where the elevator (30) is moved between an elevated position and a fallen position in a state where the engaging portion (100) is in contact with the contact portion (101). In a state where the engaging portion (100) is in contact with the contact portion (101), the wall portion (81) regulates the movement of the engaging portion (100) in a direction where the engaging portion (100) enters the opening (104) in a case where the elevator (30) is present between the elevated position and the fallen position and allows the movement of the engaging portion (100) in the direction where the engaging portion (100) enters the opening (104) in a case where the elevator (30) is present between the fallen position and an attachment/detachment position.
