PROBLEM TO BE SOLVED: To provide an endoscope bend part having a complex configuration using a plurality of types of segments which have different shapes and can be easily identified.SOLUTION: A bend part in an endoscope for observing inside a body cavity is composed of a plurality of segments in circular ring shapes. Each of the plurality of segments includes: a wire guide through which an operation wire for bending the bend part is inserted and a connection unit for connecting with an adjacent segment. The plurality of segments include three or more types of segments having difference among the types in at least one of an outer diameter, position of the wire guide, and gap amount between the connection unit and segments end face. Each of the plurality of segments can have a character index for identifying the segment.
