Endoscope and method of attaching long member

An endoscope includes a connector for connecting a movable body and a long member. The connector includes: an open-close member having a distal end portion and a proximal end portion which are opened or closed by swinging about a predetermined fulcrum, the proximal end portion having a holding portion which holds the long member when the proximal end portion is closed, the distal end portion having an engaging portion which projects outwardly in a radial direction of the distal end portion and is engageable with an inner side of the movable body; and a locking member which moves in a longitudinal direction outwardly in a radial direction of the open-close member, and locks the proximal end portion of the open-close member and the movable body with each other in a state where the long member is held.
