<p>In the present invention, a metal sheet is fixed to a heat dissipation member using three fastening members. The region of the metal sheet that is surrounded by the fastening members includes at least part of a mounting part, to which an electronic component is mounted, of the metal sheet. Thus, even if heat from the electronic component causes a force that warps a circuit board with respect to the heat dissipation member, the circuit board in the region of the metal sheet that is surrounded by the fastening members does not warp with respect to the heat dissipation member because of the fastening of the fastening members. Accordingly, the region of the metal sheet that is surrounded by the fastening members can function as a heat conveyance channel between the metal sheet and the heat dissipation member.</p> |
