PROBLEM TO BE SOLVED: To provide a small-sized electric apparatus which has a high heat radiation efficiency and is superior in an electromagnetic shield and electromagnetic durability. SOLUTION: This electric device comprises a plurality of electric parts, and a case which is composed of a conductive material and is used for accommodating or mounting the plurality of electric parts. The case has a plurality of projections for radiating heat to be generated from the electric parts in a cavity of the interior. The case is provided with an opening part for circulating a thermal conductive medium between the interior and exterior. Further, this electric apparatus comprises a plurality of electric parts and the case which is composed of a conductive material and is used for accommodating or mounting the plurality of electric parts, and there is provided an opening part capable of circulating a thermal conductive medium between the interior and exterior of the case. There is provided, in the interior of the case, partitions which are composed of a conductive material, and divide the interior of the case into a plurality of areas along a direction of a flow of the thermally conductive medium. |
