PROBLEM TO BE SOLVED: To detect a fraudulent attempt committed by making a hole in a cabinet of a game machine. SOLUTION: The game machine is provided with a wiring board 10 mounted on the rear or the side of the cabinet of the game machine and a disconnection sensing part 20 which senses whether the electric wire of the wiring board is disconnected or not. The wiring board is provided with a platelike base part and a plurality of electric wires which is arrayed on the base part longitudinally, laterally or aslant in a lattice. Each of the plurality of electric wires is connected to another one adjacent to it at each one end and to next one adjacent to it at the other end, hence being put together into one electric wire 11. The disconnection sensing part is connected to both ends of one electric wire thus obtained of the wiring board and when the one electric wire is disconnected by illegal boring, it outputs a signal to the effect.
