ABSTRACT:
In an electronic endoscope apparatus containing an objective optical system and a CCD sensor at the distal end thereof, the optical system and CCD sensor are moduled in an optical module tube. The optical module tube is first separately formed from the body of the distal end portion of the electronic scope. In the optical module tube, a focusing of the objective optical system is preadjusted with respect to the CCD sensor. Thereafter, the optical module tube containing the focus-adjusted optical objective optical system is assembled with the body of the distal end portion.
