摘要:
An endoscope includes an observation window provided on an end surface of a distal end portion of an insertion unit to introduce a reflecting light from an object to an 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.
