Abstract
An endoscope includes a distal end portion in which an optical unit and a treatment instrument channel are held such that a photographing optical axis, a central axis of the distal end portion, and a central axis of the treatment instrument channel are linearly aligned When viewed from an end face of the distal end portion. The first magnet and the second magnet are arranged at non-rotationally-symmetric positions with respect to the photographing optical axis, and a region of the optical unit, which is on a side where a distance between the first magnet and the second magnet on an arc of a circle around the photographing optical axis is short, faces the treatment instrument channel.
