The present disclosure relates to an imaging apparatus.

For example, JA 2010-213000 A discloses an imaging apparatus that cools an image sensor using outside air. Specifically, the image sensor is cooled by a Peltier element (thermoelectric element). The heat absorbed by the Peltier element from the image sensor is transmitted to the heat sink including a plurality of fins. The plurality of fins of the heat sink are cooled by the outside air blown by the cooling fan.

By the way, in a case where the image sensor is cooled using the outside air, it is necessary to take measures so that foreign matter such as dust included in the outside air does not reach the image sensor, particularly does not adhere to the light receiving surface of the image sensor. Adhesion of foreign matter such as dust to the light receiving surface may deteriorate the image quality of the captured image.

Thus, the present disclosure has an object to prevent foreign matter such as dust included in outside air from reaching an image sensor in an imaging apparatus that cools the image sensor using the outside air.
