<p>An endoscope image capture unit (30) comprises: an anchoring frame (32) which is housed in a leading end part (6) of an insertion part (9) of an endoscope (2), and retains an objective optical assembly (31) in the front side thereof; an image capture unit (35) which is positioned in the rear end side of the anchoring frame (32) and further comprises a light receiving unit (36) wherein a subject image is formed by the objective optical assembly (31); and shutter parts (38) which are disposed between illumination parts (23) and the image capture unit (35), which are positioned in the leading end part (6), are disposed to be located upon tangent lines (A, B) which join end parts of the illumination parts (23) with corner parts of the light receiving part (36), and shutter stray light from the illumination parts (23) to the light receiving part (36). Flare and other light pollution from the illumination parts to a solid-state image capture element is reliably prevented, along with deterioration in ease of assembly and increasing size in the leading end part of the insertion part also being prevented.</p> |
