Patent attributes
An electronic device includes a board to which a heat generation component is attached, a heat sink that radiates heat generated by the heat generation component, a cooling target component that is between the board and the heat sink and is attached to the board, and a duct that takes in a part of a cooling air flow for cooling at least the heat sink and introduces the cooling air flow which is taken in to the cooling target component, thereby sufficiently cooling the cooling target component that is between the heat sink increased in size and the board and is positioned on a side to which the cooling air flow being applied to the heat sink flows away from the heat sink.
