An endoscope having an insertion section and used for an endoscope device for displaying an observation image obtained by an imaging element. The endoscope has an observation window provided on a head surface of the head of the insertion section so as to introduce light from an object to the imaging element; plural illumination means for emitting light to illuminate the object, the illuminating means being provided around the observation window, on the head surface of the head of the insertion section; and a water-feeding nozzle for feeding a liquid to the surface of the observation window, the nozzle being provided on the head surface of the head of the insertion section. The axis in the substantial center of the area irradiated by the illumination means is inclined relative to the optical axis of an observation optical system so that the illumination light emitted from the plural illumination means does not hit the water- feeding nozzle. The inclination of the axis is in the direction separating from a point, ahead in the observation direction, on the optical axis of an observation optical system including the observation window. |
