An endoscope device including an insertion part including an observation optical system and a measuring optical system, wherein the endoscope device is provided with a characteristic value comparing circuit 85 which compares previous characteristic values and current characteristic values to identify previous characteristic values corresponding to the current characteristic values, and when storing the current characteristic values, current characteristic values corresponding to the previous characteristic values, identified by the characteristic value comparing circuit 85 , are stored in a storage circuit C 2 together with various information. According to the invention, for inspecting turbine blades of jet engines, automation (labor-saving) of the inspection process by reducing the number of the inspection steps is realized and the difficulty in the inspection of analysis areas is eliminated.
