According to one embodiment, an electronic device includes a housing including an opening, a partition wall which partitions an interior part of the housing into a first chamber and a second chamber which is opened to the outside through the opening, first and second heat generating parts mounted in the first chamber, a first heat radiation member located in the second chamber, a heat transfer member which transfers heat generated by the first heat generating part, a cooling fan which draws outside air and exhausts the air against the first heat radiation member, a second heat radiation member which is exposed to the outside of the housing and is thermally connected to the second heat generating part, and a cover covering the opening and the second heat radiation member. The cover forms a gap between the cover and the housing. The gap communicates with the second chamber.
