Abstract
An image capturing apparatus improved in heat dissipation efficiency while avoiding increase in size. A rotary fan is rotated to draw air from a suction port and discharge air from a discharge port. A heat dissipation duct includes an intake opening, a discharge opening, intake-side fins, an intake-side duct portion, and an exhaust-side duct portion. Projected shadows of at least part of the intake-side fins and at least part of the rotary fan overlap each other, as viewed from a direction of a rotational axis of the rotary fan. Ends of the intake-side fins toward the intake opening and the exhaust opening are closer thereto than ends of the rotary fan toward the same, respectively. The intake opening and the suction port of the rotary fan communicate with each other via a space adjacent to the end of the intake-side fins toward the discharge opening.
