DISTAL END PORTION OF ENDOSCOPE
First Claim
1. A distal end portion of an endoscope comprising:
- an insertion portion to be inserted into a body to be examined;
a projecting face which is provided at a distal end portion of the insertion portion in a projecting manner and on which an observation portion for observing the body to be examined is disposed; and
a nozzle portion which is provided on a non-projecting face of the insertion portion for delivering fluid to the observation portion.

Abstract
An air-supplying/water-supplying nozzle for delivering fluid to a second imaging unit for observing a body to be examined which is provided at a distal end portion of an insertion portion to be inserted into a body to be examined in a projecting manner is provided on a non-projecting face of the insertion portion, the non-projecting portion being disposed at a position lower than a flat face of a middle step portion on which the second imaging unit is disposed. Thereby, such a possibility can be reduced that an opening portion of the air-supplying/water-supplying nozzle is caught by an object to be examined and observation or diagnosis work conducted using an observation optical system of an object-contacting type can be conducted.
