PROBLEM TO BE SOLVED: To provide a slave endoscope in a parent-child endoscope system in which a direction around the axis of an insertion part inserted into a treatment instrument insertion channel of a master endoscope can be visually recognized by an X-ray image during contrast examination under fluoroscopy so that a direction that a curved part can curve can be easily discriminated.SOLUTION: A slave endoscope 2 in a parent-child endoscope system 40 includes: an insertion part 10 that is freely inserted into and removed from a treatment instrument insertion channel 8 of a master endoscope 1; a curved part 17 arranged on a leading end side of the insertion part 10 that can be freely curved in a predetermined direction; and an X-ray non-transmission marker 60 for discriminating the curvature direction of the curved part 17 by being provided to the curved part 17 and displayed in an X-ray image. |
