Abstract
An endoscope insertion portion of this invention includes an air/water feeding portion for spouting gas or liquid from a spouting port to outer surfaces of the first observation optical system and the second observation optical system, which is disposed on the distal end portion so as to line up with the first observation optical system and the second observation optical system on a generally straight line. The air/water feeding portion is disposed on the distal end portion such that a spouting direction of the gas or the liquid has a first angle with respect to the first direction.
