摘要:
An endoscope apparatus includes: a transparent member provided at a distal end of an insertion portion of an endoscope, opposed to an image pickup optical system a transducer provided on one face of the transparent member and an elastic member that is provided at a location to which ultrasound vibrations from the transducer are transmitted, and for which a physical property value changes accompanying a temperature change. Thus, the endoscope apparatus suppresses excessive heat generation of a transducer for removing dirt that adheres to an observation window, and prevents damage to the transducer as well as a deterioration in the characteristics thereof.
