Endoscope

Abstract

Provided is an endoscope in which unevenness of illumination light is not likely to occur. An endoscope includes: a translucent tubular distal end cover disposed at a distal end of an insertion portion; a tubular fixation frame in which the distal end cover is fixed on a distal end side thereof; and a tubular illumination frame fixed to an inner peripheral surface of the fixation frame and holding a light source at a distal end thereof, in which a predetermined gap is provided between an inner surface of the distal end cover and surfaces of the illumination frame and the light source. The endoscope further includes an observation window protruding from the distal end cover, in which the distal end cover includes an illumination lens unit that transmits illumination light emitted from the light source and illuminates a visual field direction of the observation window.
