CONSTITUTION:A cover 18 as a covering member is constructed by: a leading tube portion 11 for covering a leading tube 1; a lever portion 12; a forceps mouth portion 13; a movable portion 14; a zipper 15; and fixing rings 16 and 17 as fixing members. An end surface of a front end hard portion 9 and a forceps mouth 7 of the leading tube 1 can be exposed from openings formed at the end of the leading tube portion 11 and the forceps mouth portion 13. The fixing ring 17 is arranged so that the body fluids of a subject to be examined do not invade inside the cover 18 and watertightness is assured by fastening the cover and the side of the front end hard portion. The forceps mouth portion 13 is obtained by folding the cover 18 toward the inside the opening of the cover 18 and a cap 19 having the forceps mouth 7 and a liquid injection inlet 8 is fit into the forceps mouth 13, thereby assuring the watertightness between the opening portion and the cover 18.

Then, plural electric potential electrodes 2b are mounted along the high molecular layer 3, and moreover, a common electrode is set facing the respective electric potential electrodes 2b across the high molecular layer 3. Now, if any of the respective electric potential electrodes 2b is exerted the voltage, the position of the electrode on the high molecular will have a different coefficient for an easier bend. Accordingly, by chosing any of the electric potential electrodes 2b to exert voltage, the scope is able to be curved at a desired position of the winding part of the end.
