Abstract
An endoscope apparatus includes a transparent member provided at a distal end of an insertion portion of an endoscope to face an image pickup optical system, an ultrasonic transducer attached to an inner surface of the transparent member, and a deflection portion provided at an outer surface of the transparent member which changes a direction of propagation of an ultrasonic wave from the ultrasonic transducer. With the configuration, an ultrasonic wave for stain removal is efficiently propagated from the ultrasonic transducer into a region of an observation field of view in an observation window.
