Claim Text:
1. An endoscope comprising: an elongated member having a distal end section and a proximal end section, the elongated member including a first insertion section, a second insertion section having a distal end side corrugated tube, which extends along the longitudinal axis, and a proximal end side corrugated tube, which is rotatably attached to a proximal end portion of the distal end side corrugated tube so that the proximal end side corrugated tube rotates about a central axis of the proximal end side corrugated tube relative to the distal end side corrugated tube, a branch section having an insertion hole that communicates with the channel of the first insertion section such that the proximal end side corrugated tube protrudes radially outward from the channel in a state when the second insertion section is inserted into the channel, an active bending section disposed at a distal end portion of the distal end side corrugated tube, the active bending section being capable of bending; a stick configured to be inclinable so as to bend the active bending section; and a swing mechanism disposed at the proximal end side corrugated tube, the swing mechanism being configured to support the stick such that the stick is inclinable on two planes that are perpendicular to each other and cross each other,
