Abstract: The ultrasonic endoscope includes: an elongated insertion part having a longitudinal axis and a distal end hard portion provided on a distal end side; an ultrasonic transducer that is provided in the distal end hard portion, and transmits and receives an ultrasonic wave; and a supply port that is provided in the distal end hard portion and supplies water into a balloon surrounding the ultrasonic transducer, in which an indicator indicating a position of the supply port in a peripheral direction around the longitudinal axis is provided on a proximal end side of the insertion part with respect to the distal end hard portion.

Abstract: Operability in inserting an insertion part of an endoscope into a body cavity using an insertion assisting tool is improved. In an insertion assisting tool 60, a sidewall portion of a tube main body 64 through which an insertion part 12 of an endoscope 10 is passed is provided with a sidewall opening part 68 having a size in which the insertion part 12 can pass through. A distal end side of the sidewall opening part 68 is provided with a guiding valve 82, and the insertion part 12 is guided by the guiding valve 82 to be easily fed from the sidewall opening part 68. The guiding valve 82 is swingably supported, and when the insertion part 12 is fed from a distal end opening part 67 of the tube main body 64, allowing the parallel state of being substantially parallel to an axial direction of the insertion part 12 and passing the insertion part 12 to a distal end opening part 67 side are enabled.
