In order to solve the above problem, according to one aspect of the present disclosure, provided is an imaging apparatus including: a lens attachment portion to which a lens is attached; an image sensor on which light transmitted through a lens attached to the lens attachment portion is incident; a heat transfer member configured to support the image sensor and to absorb heat of the image sensor; a main frame including a duct in which outside air flows and provided with a through hole through which a part of the heat transfer member passes; a fan arranged in the duct; a front frame configured to support the lens attachment portion and the heat transfer member and to be attached to the main frame; and a seal member configured to block a flow of outside air from inside the duct toward the image sensor through the through hole.

According to the present disclosure, in the imaging apparatus that cools the image sensor using the outside air, it is possible to prevent the foreign matter such as dust included in the outside air from reaching the image sensor.
