<p>An electronic device and a printed circuit board unit are provided to reduce the thickness of the electronic device and efficiently circulate an air current formed along the backside of a printed circuit board to cool electronic components mounted on the backside of the printed circuit board effectively. An electronic device includes a fan and a printed circuit board(22). The fan defines a protrusion projected from a flat face by a housing(29). The printed circuit board defines a notch which accommodates the protrusion of the housing and receives the flat face of the housing around the protrusion. The height of the housing from the surface of the printed circuit board is restricted to achieve a thin electronic device. The notch is easily formed on the printed circuit board.</p> |
