Abstract
An ultrasonic endoscope includes an insertion section, an operation section, an optical observation system, and an ultrasonic observation system. The optical observation system is disposed in the insertable section, and has an objective lens located on a face of a distal end of the insertion section. The ultrasonic observing system is disposed in the insertion section, and has an ultrasonic transducer disposed on the face of the distal end of the insertion section or further forward than the distal end.
