<P>PROBLEM TO BE SOLVED: To provide an endoscope light guide flexible tube satisfying any required capability different in each region. Ž<P>SOLUTION: The light guide flexible tube 10 includes a bending limited region 18W and a flexible region 18F disposed at both ends. In the bending limited region 18W, a plurality of segment members 20 are connected to each other via tongue pieces 20P in such a way as relatively rotatable. As a result, the bending property of the bending limited region 18W is limited to be bent in a prescribed direction only at a relatively large bending radius. On the other hand, the flexible region 18F can be bent in any direction till the bending radius is reduced. In this way, the bending limited region 18W where the bending property is limited is disposed in a prescribed area only, and as the area other than the bending limited region 18W is the flexible region 18F, the light guide flexible tube 10 is excellent both in the durability and in the operability.
