<p>An endoscope has an insertion unit and is used for an endoscope apparatus which displays an observation image obtained by an imaging device. The endoscope includes an observation window provided on an end surface of a distal end portion of the insertion unit to introduce a reflecting light from an object to the imaging device; a plurality of illuminating units, for emitting illumination light for illuminating the object, provided around the observation window at the end surface of the distal end portion; and a water feeding nozzle, for feeding liquid to a surface of the observation window, provided on the end surface of the distal end portion of the insertion unit. An axis substantially positioned at a center of an illuminating range of the illuminating unit is inclined in a direction away from a distal end of an observing direction of an optical axis of an observation optical system including the observation window, with respect to the optical axis of the observation optical system, so that the illumination light emitted from the plurality of illuminating units does not hit the water feeding nozzle.</p> |
