IMAGING PART OF ELECTRONIC ENDOSCOPE

摘要

PROBLEM TO BE SOLVED: To provide an imaging part of an electronic endoscope which does not generate the degradation or damages or the like of an imaging surface when heated inside an autoclave device or the like even when it is the imaging part of the electronic endoscope structured such that a solid-state imaging element unit of an independently tightly sealed structure is attached to the rear end part of an objective optical system unit. SOLUTION: In the imaging part of the electronic endoscope provided with the solid-state imaging element unit 10 structured such that the imaging surface 11a is airtightly sealed with cover glass 14 arranged facing it and is independently tightly closed as a unit and the objective optical system unit 9 structured such that the distal end part is airtightly sealed with a first lens 41 and the rear side part is airtightly sealed with the solid-state imaging element unit 10 and tightly closed, a gas is enclosed in the internal space P of the solid-state imaging element unit 10 by an air pressure lower than the atmospheric pressure at a normal temperature.
