An electronic apparatus includes a shelf part and multiple units mounted in the shelf part. Each unit includes first and second faces opposite each other, a cooling fan, and a third face different from the first and second faces. The first face has an inlet and the second face has an outlet. A cooling fan cools a circuit board inside the unit by letting in cooling air from outside through the inlet and letting out the cooling air through the outlet. The third face has an opening so that the space inside the unit communicates with the space inside the shelf part through the opening.
