Abstract

An optical adaptor and an endoscope device provides a means which can identify an optical adaptor to be used accurately, thus enabling misoperation by a user to be prevented. A construction is adopted wherein an optical adaptor incorporates an IC chip in which identification information and optical characteristic information of the optical adaptor is stored, and the tip of an endoscope insertion section is provided with an antenna which obtains the identification information and optical characteristic information from the identification IC chip.
