PROBLEM TO BE SOLVED: To provide an ultrasonic observation device that can surely prevent a liquid from entering the inside of a holding part for holding an ultrasonic wave transmitting/receiving part.SOLUTION: The ultrasonic observation device incudes: the ultrasonic wave transmitting/receiving part for transmitting/receiving an ultrasonic wave in an ultrasonic wave transmitting/receiving region which is a predetermined region in an ultrasonic wave transmitting/receiving surface; the holding part for holding the ultrasonic wave transmitting/receiving part so as to expose the ultrasonic wave transmitting/receiving region; an acoustic lens part which is adhered on the ultrasonic wave transmitting/receiving surface by a first adhesive so as to cover the ultrasonic wave transmitting/receiving region; and a protection part which covers an outer peripheral part not covered with the acoustic lens part on the ultrasonic wave transmitting/receiving surface, is disposed to extend in the outer peripheral direction from the ultrasonic wave transmitting/receiving surface, is adhered on the acoustic lens part and the outer peripheral part by a second adhesive and is adhered integrally with the holding part or on the holding part by the second adhesive. |
