The thermal conductive sheet 133 may be attached to one surface of the shielding case 140. When the shield case 140 is not mounted on the printed circuit board 118, the thermal conductive sheet 133 may be directly attached to the electronic element 101 or may be attached through a heat radiation pad.

As illustrated in FIG. 7, the heat radiating pad 141 may be in contact with the inner surface of the shielding case 140, and the heat conductive sheet 133 may be attached to the outer surface of the shielding case 140. In this case, heat emitted from the electronic device 101 is transferred to the heat conductive sheet 133 via the heat dissipation pad 141 and the shielding case 140.

Meanwhile, as shown in FIG. 8, the shielding case 140 may have a through area 142 for exposing at least a portion of the heat dissipation pad 141, and the heat conductive sheet 133 may have a heat dissipation through area 142. It may be attached to or in contact with the heat radiating pad 141. In this case, heat emitted from the electronic device 101 is directly transferred to the heat conductive sheet 133 via the heat dissipation pad 141. Accordingly, the efficiency of heat transfer conducted from the electronic device 101 to the heat conductive sheet 133 may be further improved.
