Abstract: [Overview] [Problem to be Solved] To make it possible to appropriately rotate an endoscope.
[Solution] There is provided an endoscope including: a main body including a coupler to which a cable is attached; a tubular section having a tubular form; a reflector having a reflection surface that reflects light introduced from the coupler to inside of the main body and introduces the light to inside of the tubular section; a first optical system that transmits the light introduced by the reflector to the inside of the tubular section to a front-end portion of the tubular section and irradiates a subject with the light from the front-end portion; and a second optical system that transmits reflected light of the subject from the front-end portion of the tubular section to the main body side. The coupler is provided to be rotatable in the main body around a central axis of the tubular section with respect to another portion. The cable being coupled to a light source. The tubular section is fixed to the main body and extends from the main body.
