PROBLEM TO BE SOLVED: To provide an endoscope which is free from inconvenience such as breakage of element wires of a cylindrical network member, heavy power required for bending operation, etc. and further in which a wide change of bending resistance can be easily set up. SOLUTION: A flexible cylindrical network member is covered on the outer periphery of a bendable core material. A bending part 8 covered by an envelope is equipped on the outer periphery of the network member. Node rings 35 of the core material are arranged in a row in the axial direction of the bending part 8. Neighboring node rings 35 are mutually rotatably combined. A resin-coated part wherein flexible resin 53 is coated on the cylindrical network member 50 is provided. The border between the resin-coated part and an uncoated part which is not coated by the resin is positioned on a circumferential face of the node rings 35. COPYRIGHT: (C)2006,JPO&NCIPI
