PROBLEM TO BE SOLVED: To facilitate the maintenance of a first ring, an angle ring connected to the tip body of an endoscope, and to enlarge the inner volume of the first ring located behind the tip body by forming a groove on the outer surrounding surface of the first ring and fixing an operation wire to the groove to make the angle part and the tip body easily separable. SOLUTION: A part of upper/lower and left/right operation wires 13 to be curved by the remote-control of the angle part 2b is transferred from a gap between the first ring 18-1 and a second ring 18-2 to the outer surface of an flexible tube 19. The tip of the operation wire 13 is stored in the groove 20 and fixed by means of soldering or brazing, or the like. The end of a net 10 to be attached to the first ring 18-1 is fixed by the soldering and the fixed part is extended to the operation wire 13. A cutout 21 for the operation wire 13 to be inserted thereinto is formed in the second ring 18-2 on the side facing the first ring 18-1 to prevent the operation wire 13 from being caught.
