According to one embodiment, an electronic device includes a cooling fan which is arranged in a case, a space being present between heat radiation fins and the cooling fan, and a case-contained member contained in the case. The case includes a second member which is detachably coupled to a first member and faces the space. The case-contained member faces the space on the side opposite to the second member. When the second member is coupled to the first member, the second member and the case-contained member cooperate to form a duct which guides air exhausted from the cooling fan to the heat radiation fins.
