Image pickup apparatus with forced air-cooling structure

An image pickup apparatus comprising:

• an image pickup element configured to photoelectrically convert an object image formed, by a shooting optical system;
• a first circuit board arranged along in an optical axial direction of the image pickup element;
• a second circuit board arranged along the optical axial direction in parallel with the first circuit board;
• a fan;
• an inlet arranged on one side of an apparatus body of the image pickup apparatus in a width direction, said inlet being configured to inhale external air by drive of said fan;
• an outlet arranged on the one side of the apparatus body in the width direction, the outlet being configured to discharge the air inhaled through said inlet by the drive of said fan;
• and
• a duct provided inside of the apparatus body while extending along in the optical axial direction, said duct having an inhaling part interconnecting with said inlet, a discharging part interconnecting with said outlet, and a cooling part connected to each of the inhaling part and the discharging part,
• wherein each of the inhaling part and the discharging part is connected to the cooling part in a direction intersecting with the cooling part,
• wherein the first circuit board is arranged on a surface of a side of the cooling part, on which said inlet and said outlet are open, and the second circuit board is arranged on a surface of a side of the cooling part, opposite to the surface on which the first circuit board is arranged.
