PROBLEM TO BE SOLVED: To provide a game machine having a convenient fraudulence preventing means capable of being inexpensively manufactured and capable of easily discovering fraudulence. SOLUTION: A first case part 4 and a second case part 5 are formed to be closed to each other to house a control board, and a microchip MC is fixed within a hole 13a of a pipe 13 formed in the second case part 5. The microchip MC includes a transparent substrate MCa to be fixed to the hole 13a, and a recording layer MCb to record information, a reflection layer MCc, a protection layer MCd and an adhesive layer MCe which are layered on the transparent substrate MCa. When the first case part 4 and the second case part 5 are closed, the adhesive layer MCe adheres to a plate surface AR of the control board housed in the first case part 4. If the first and second case parts 4 and 5 are opened by a fraud doer, the recording layer MCb and the reflection layer MCc formed in the microchip MC are released and broken. By seeing the broken area through the transparent substrate MCa, the performed fraudulence can be easily recognized. COPYRIGHT: (C)2010,JPO&INPIT
