PROBLEM TO BE SOLVED: To provide a game machine capable of preventing a member for sealing a control substrate from being fraudulently opened without lowering productivity and workability. SOLUTION: A Pachinko machine 10 has an outer frame 11, an inner frame 12 openably and closably disposed at one side of the front portion of the outer frame 11, and a front surface frame set 14. A game board is fixed to a rear side of the front surface frame set 14. A substrate box comprising a box base and a box cover, and sealing a main control unit therein by attaching and fixing both with countersunk screws is disposed in the rear side of the game board. Through holes for passing through the countersunk screws are formed in the box base, and boss holes formed so as to oppose to the through holes and through which the countersunk screws are passed are formed in the box cover. Further, the countersunk screws have each a hexagonal hole in its head end surface, the hexagonal hole is closed by forcing a filling material into the hexagonal hole in the attached state of the countersunk screw.
