<p>PROBLEM TO BE SOLVED: To provide an electronic apparatus, in which even a CPU of a BGA can be cooled efficiently by a method, wherein the CPU in which a weighting limit is installed can be thermally connected stably within the weighting limit. SOLUTION: A first heat sink 25 is mounted on a CPU 23 via a heat transfer sheet 26, A plurality of heat transfer parts 25a are formed on the first heat sink 25. A second heat sink 27 is arranged on the first heat sink 25. Opening parts 29, into which the heat transfer parts 25a can be inserted by keeping a gap, are formed in the second heat sink 27. Heat conductive grease is filled between the heat transfer parts 25a and the opening parts 29.</p> |
