Abstract

A curved tube (52) in an endoscope is formed by flexibly connecting curved pieces (62) in order along the axial direction of the insertion part (12) of the endoscope (10). The curved piece includes slits (82a, 82b, 86a, 86b) and recesses (84). The slits (82a, 82b, 86a, 86b) are formed in the direction crossing the axial direction of the curved piece between one side (64a) and the other side (64b) of the base (64) and allows a part of an operation wire (50) to be extended from the outside to the inside of the curved piece, and the recesses (84) are so provided adjacent to the slits as to be recessed inward from the outer peripheral surface of the curved piece.
