To provide a low-cost enclosure which prevents electromagnetic noise emitted from an electronic device placed in an enclosure body from escaping out of the enclosure body from an opening, and prevents a temperature increase in the enclosure body.
The enclosure includes the enclosure body 1 which houses the electronic device 5 and has projections 3, 4 reflecting electromagnetic noises 6 on the interior periphery of the enclosure body 1 and the opening 2 open to the outside at a necessary spot, an electromagnetic wave absorber 7 placed in the enclosure body 1, and a channel 9 through which a cooling medium 8 cooling the electromagnetic wave absorber 7 circulates. The electromagnetic noises 6 emitted from electronic device 5 are reflected by the projections 3, 4, and then are absorbed by the electromagnetic wave absorber 7.
