Image pickup apparatus having heat radiation structure

An image pickup apparatus comprising:

• a grip portion including a protrusion portion protruding toward a subject side in an optical axis direction of the image pickup apparatus, the grip portion being provided at an end portion of a main body;
• a medium circuit board on which a medium accommodation portion for accommodating a recording medium is mounted, the medium circuit board being disposed behind the protrusion portion in the optical axis direction;
• a main circuit board disposed substantially orthogonal to the optical axis;
• a cooling duct including a first extension portion, the cooling duct being thermally connected to the medium circuit board and the main circuit board;
• and
• an air cooling fan configured to introduce air into the cooling duct,
• wherein the first extension portion is located in the grip portion between the protrusion portion and the medium circuit board, and extends in a direction substantially parallel to the optical axis direction, and
• wherein a part of the air cooling fan is disposed in the protrusion portion.
