Abstract
In an endoscope apparatus, an optical end adapter is detachably attached to the end portion of an elongated inserting section, and an endoscope insertion aid is detachably provided which has the minimum diameter which is smaller than the maximum outer diameter of the optical end adapter. The endoscope insertion aid is fitted onto the inserting section from the leading end thereof, and then the optical end adapter is attached. It is, accordingly, possible to positively prevent the endoscope insertion aid from coming off the optical adapter.
