PROBLEM TO BE SOLVED: To provide a circuit board cooling structure for a game machine which can solve the problem that the function of a circuit is stopped due to high temperature by efficiently cooling the circuit board which is attached onto the rear surface of the game machine and is covered by a cover even when the circuit board is arranged in a small space at the rear surface of the game machine. SOLUTION: This structure is provided with: upper and lower communication chambers 65, 62 for permitting the communication between spaces 63, 64 above and below the parts mounting surface side and soldering surface side of the circuit board 32; an upper ventilation passage 66 for permitting the communication between an upper opening 14 formed in upper front of the game machine and the upper communication chamber 65; and a lower ventilation passage 61 for permitting the communication between a lower opening 16 formed in lower front of the game machine and the lower communication chamber 62. The thermal exchange destination of air at the part mounting surface side and soldering surface side of the circuit board 32 where the temperature is raised is defined not as a space in a game machine island but as a space at the side of a player passage, so that the circuit board 32 is efficiently cooled.
