鏡スコープ。[Claims for Utility Model Registration] An ultrasonic transducer installed in a rotary holder for mechanical scanning transmits and receives an ultrasound beam to a diagnostic site within the subject, displays an ultrasound tomographic image, and displays the diagnostic site. In an ultrasound endoscope that visually observes a diseased area by irradiating a guide light onto the oscillator, the guide light is irradiated from an exit hole penetrated through the approximate center of the transducer in the same direction as the ultrasound beam irradiation direction. 1. An ultrasonic endoscope, characterized in that the laser beam is emitted by a laser beam generator fixedly attached to the rotary holder so as to emit a laser beam as light.
