Abstract
There is provided an electronic apparatus that is free of the problems with the prior art and is capable of achieving higher efficiency of cooling the interior of the casing without sacrificing cost reduction and designing compact in size. A casing houses a plurality of circuit boards having electronic parts mounted thereon and at least one high load part that generates heat. The casing has exhaust ports formed therein for heat radiation and exhaust ports for heat radiation. The plurality of circuit boards are comprised of a first circuit board and a second circuit board. The first circuit board is disposed to extend substantially horizontally, and the second circuit board is disposed to extend substantially vertically with a horizontal gap provided between the first circuit board and the second circuit board. The at least one high load part is arranged below the horizontal gap, and the exhaust ports are arranged above the horizontal gap.
