<P>PROBLEM TO BE SOLVED: To provide an electronic component capable of reducing radiation of unnecessary electromagnetic waves and capable of radiating heat easily and inexpensively. <P>SOLUTION: A heat conduction sheet 2 is attached between a heat sink plate 1 and the heat sink plate attachment surface of an electronic component 3. The heat sink plate attachment surface of the electronic component 3 is constituted so that it can recognize a noise generating source 4 arranged in the electronic component 3. For the heat conduction sheet 2, a through hole 21 is formed in the upper position of the noise generating source 4. The through hole 21 is located between the heat sink plate 1 and the electronic component 3 to form a noise attenuation space. An electromagnetic noise generated from the noise generating source 4 generates propagation loss and propagates it to the heat sink plate 1 by propagating the noise attenuation space with the through hole 21 and by propagating the heat conduction sheet 2 which is attached separately from the noise generating source 4. Therefore, the electromagnetic noise emitted from the heat sink plate 1 is reduced. Moreover, the heat generated from the electronic component 3 conducts the heat conduction sheet 2 and the noise attenuation space and is radiated from the heat sink plate 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
