TIP PART OF ENDOSCOPE WITH JACKET SHEATH

摘要

PROBLEM TO BE SOLVED: To provide a tip part of an endoscope with a jacket sheath capable of obtaining clear endoscopic observation images without ghosts or flares by preventing light emitted from an illumination window from reaching an observation window through a gap part even when there is a gap between the back surface of the jacket sheath and the surface of a tip part body between the illumination window and the observation window. SOLUTION: In the tip part of the endoscope with the jacket sheath having the gap A between the back surface of the jacket sheath 11 and the surface of the tip body 2 between the illumination window 4 and the observation window 3, a part 11a from the part facing the illumination window 4 on the back surface of the jacket sheath 11 to a part near the side of the observation window 3 is formed in a slope shape gradually approaching the surface side of the tip part body 2 as approaching the side near the observation window 3.
