An insertion unit in which an image transmitting optical fiber bundle and an illumination light transmitting optical fiber bundle are incorporated is detachably coupled with the operation unit through a coupling unit. The insertion unit is bent using a bending wire attached to the distal end thereof and coupled to the operation unit by a wire operating mechanism. An anti-clouding material can be disposed on a surface of the distal end of the insertion unit to protect it against clouding.
