PROBLEM TO BE SOLVED: To correctly measure the length of a bile duct or the like and to eliminate fear of damaging and injuring an endoscope internal part and a human body internal part by providing marker parts where a linear radiation non- permeable member is spirally wound in the outer periphery of an endoscope treatment implement and a coating part which is made to be smooth after coating in the outer periphery. SOLUTION: A tube 1 is rotated while moving in an axial direction by a table, the non-permeable member 3 is spirally wound in the outer periphery and, then, the marker parts 4, 4a and 4b are easily fixed. Moreover, the movement amount of the tube 1 is controlled so that the marker parts are formed by desired length in the axial direction. Besides, the marker parts are formed by changing a spirally rotating pitch so that the flexibility of the tube 1 is freely obtained. Then the table is moved with precision and an inter-marker pitch is made to be stable. The tube 1 and the outer periphery of the non- permeable member 3 are coated so that projections and recessions on the respective marker parts are smoothed. |
