An endoscope is provided, with a main body and a rigid shaft, extending from the main body, which has a first section which extends in a rectilinear manner, a curved second section adjoining it and a third section, adjoining the second section, which forms a distal end of the shaft. The shaft includes, for receiving an instrument, a one-piece instrument tube which extends to the distal end of the shaft and has an open end there, and an optics module by means of which an image of an area in front of the distal end of the shaft can be recorded. A cladding tube extending from the main body to the distal end is provided, in which the instrument tube and the optics module are arranged, and which includes a rectilinear part for the first section and a curved part, connected to the rectilinear part, for the second section.
