An electronic apparatus capable of separating and dissipating heat generated by a plurality of heat sources. The electronic apparatus includes a main circuit board and an image pickup device unit, as heat sources. A first duct unit is disposed between the main circuit board and the image pickup device unit, and dissipates heat from the image pickup device unit to an outside. A second duct unit is disposed at a position where the second duct unit and the first duct unit sandwich the main circuit board, and dissipates heat from the main circuit board to the outside.
