An electronic device includes a casing and a fan received in the casing. The fan includes a cover plate, a bottom plate and a side wall. An air outlet is defined in the side wall. The bottom plate defines an air inlet. The casing includes a bottom cover and a top cover. The bottom cover includes a base plate, and a side plate extending upwardly from a periphery of the base plate. The bottom plate includes a horizontal first area and a second area inclining relative to the first area. A height of the base plate relative to a horizontal plane gradually increases from one side of the casing to another side of the casing. A height of the second area relative to the horizontal plane also gradually increases from the one side of the casing to another side of the casing.
