An endoscope angle portion comprises an angle portion structure. The angle portion structure includes angle ring units each of which comprises pivoting joint portions extending from its both ends and has a shape that is notched obliquely in directions away from the pivoting joint portions, and wherein adjacent ones of the angle ring units is pivotally joined to form the angle portion structure, wherein a first angle ring unit of the angle ring units has a larger length dimension than that of a second angle ring unit of the angle ring units, and the first angle ring unit has a smaller notch width of a notched portion than that of the second angle ring unit, the first angle ring unit being nearer a base end of the endoscope angle portion than the second angle ring unit.
