Abstract
A front end hood for an endoscope allows an observation image of a portion which is transmitted through the transparent front end hood to be less distorted, and produces an excellent observation image even in a periphery of a wide visual field. An optically transparent front end hood projects from a front end insertion portion of an endoscope so that an observation port located in the front end face of the front end insertion portion is positioned inside the front end hood. A portion of the front end hood may be formed into a spherical shape, the diameter of which decreases toward the opening end of the front end hood.
