Provided is a medical endoscope in which a doctor can easily notice a change in internal air pressure.

A pressure sensor (10) for detecting a pressure of a gas supplied to a surgical site in a body is arranged in an imaging field of view of a camera of a medical endoscope, and the pressure sensor (10) converts the pressure in the body into five sensory information. Specifically, the cylindrical cover (5) is mounted on the front end portion of the lens barrel (2), and the pressure sensor (10) is mounted on the inner wall surface of the cover (5). The pressure sensor (10) can convert the air pressure in the body into a color, and since the color enters the camera field of view, the doctor can intuitively judge the pressure change in the surgical field of view on the monitor. Therefore, even if the focus is on surgery, it is easy to monitor pressure changes. In addition, since the wiring for the pressure sensor (10) is not required, the outer diameter of the electronic oscilloscope can be reduced.
