Abstract
There is provided a bending portion for an endoscope and the endoscope which can prevent the piece fall of bending pieces without enlarging the diameter of the bending portion and raising the filling rate of built-in components in the bending portion. In the bending portion, one bending piece of adjacent bending pieces is formed so that a cross-sectional shape is, for example, an elliptic shape whose major axis direction or minor axis direction corresponds to a first direction. The other bending piece of the adjacent bending pieces is formed so that a cross-sectional shape is, for example, a circular shape in which a length in the first direction differs from the first bending piece; and an abutting portion in which their end portions facing each other of the adjacent bending pieces abut on each other in at least two points when the bending portion is bent.
