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: Flange parts 12 and 13 are formed in first case part 4 and second case part 5 respectively to be closed to each other to house a control board. A microchip MC is inserted and fixed into a hole 13a formed in the flange part 12. 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 the surface of the flange part 12. 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
