Abstract: Provided is an ultrasound endoscope capable of achieving both improvement of the kink resistance of a forceps tube in a bending part and improvement of electromagnetic wave shieldability in a distal end hard part.
A forceps tube is configured such that a metal element wire is wound around a tube bending part that is disposed inside a bending part, and a tube distal end part including an opening portion facing region facing an opening portion of a shield ring is formed of a material that is hardly influenced by electromagnetic waves. The tube distal end part is configured of only the forceps tube. That is, the metal element wire that is influenced by electromagnetic waves is not wound around the tube distal end part, and resin, such as fluororubber or silicon rubber, to be hardly influenced by electromagnetic waves is exposed from the opening portion facing region.-
