PROBLEM TO BE SOLVED: To provide a forcible air-cooling structure which produces no wasteful air flows which are not contribute to the cooling of an electronic element and is improved in cooling efficiency and to provide a game machine. SOLUTION: LSIs 25 and 26, a heatsink 31, and a cooling fan 32 are provided so as to overlap with each other in a plane vision, and the heatsink 31 is arranged between the LSIs 25 and 26 and the cooling fan 32. At this point, the heatsink 31 has a plane shape larger in size than the cooling fan 32 and an outer extension 33 that protrudes outward from the periphery of the cooling fan 32. A swelling part 39 protruding toward the outer extension 33 of the heatsink 31 is provided to a cover member 22 covering the LSIs 25 and 26, so that the cooling air flows produced by the cooling fan 32 are restrained from being diverted from the heatsink 31.
