The purpose of the present invention is to provide an endoscope which ensures excellent operability, retains the small size thereof, and is capable of contributing to a reduction in production costs. Accordingly, this endoscope is provided with: a bending part (7) which is provided to an insertion part (2), and which is capable of bending a pulling member (35) which moves inside the insertion part in order to bend the bending part an operation unit (3) provided with a first operation part which is connected to a base end of the insertion part, operates movement of the pulling member, and forms one side of the operation unit with respect to a central axis extending along the length direction, and a second operation part which forms another side of the operation unit with respect to the central axis, and which is formed so as to be shorter than the first operation part in the central axis direction a pulling-member adjustment unit (50) which is provided to the first-operation-part side and the second-operation-part side inside the operation unit, and which adjusts the movement range of the pulling member a first fixation member (52a) which fixes the pulling-member adjustment unit to the inside of the first operation part, and which is provided to the first-operation-part side inside the operation unit and a second fixation member (52a) which fixes the pulling-member adjustment unit to the inside of the second operation part, has the same shape as the first fixation member, is formed separately from the first fixation member, and is provided at the second-operation-part side inside the operation unit so as to be asymmetric to the first fixation member with respect to the central axis.Lobjectif de la présente invention est de fournir un endoscope qui assure une excellente maniabilité, maintienne une taille réduite, et puisse contribuer à une réduction des coûts de production. En conséquence, cet endoscope comporte : une partie de cintrage (7) raccordée à une partie dins
