PROBLEM TO BE SOLVED: To provide an endscope for observing ultrasonic wave that can provide ultrasonic tomography image in an optical observation range in the front of the tip of an insertion portion by using an ultrasonic probe transmitting, receiving, and scanning the ultrasonic wave to the side part of the tip. SOLUTION: An optical observation means 2 placed at the tip 1 of an insertion portion of an endscope so as to observe its front portion, a probe insertion channel 11 inserted and arranged in the insertion portion of the endscope so as to insert an ultrasonic probe 100, and a probe induction means 10 arranged in the insertion portion of the endscope so as to project the tip of the ultrasonic probe 100 inserted into the probe insertion channel 11 sideward from the insertion portion of the endscope are provided. |
