Abstract
It is provided an endoscope apparatus including an observing device that displays an observation view area. The observation view area is displayed on the observing device of this endoscope as a non-circular observed image. A hood member is mounted on an end of an inserted section of the endoscope and includes a hood section projecting in the direction of the observation view area. At least a part of the hood section is provided with a slope that is shaped so as to correspond to the observation view area.
