A wire member 50 is received in a flexible part 22 of an endoscope 20 and adapted to remotely curvilinearly control a bendable part 27 at a distal end of the flexible insertion part 22. The wire member 50 includes a braid 51 braiding from a plurality of resin fibers and an adhesive agent 52 impregnated in the braid 51 and hardened. The impregnating and hardening of the adhesive agent 52 are carried out in a state where the braid 51 is applied with a tensile force having a predetermined magnitude.
