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 the first and second case parts 4 and 5 respectively in which a control board is housed, and microchips MCD are fitted and fixed into holes 13aa and 13bb formed in the flange part 13. However, the positional relations between the respective microchips MC mounted in the flange part 13 are not disclosed. When the first and second case parts 4 and 5 are closed, an adhesive layer MCDe adheres to the surface of the flange part 12. Further, if the first and second case parts 4 and 5 are opened, a first recording layer MCDb and a second recording layer MCDe formed in each microchip MCD are broken and released from a first reflection layer MCDc and a second reflection layer MCDf, so that the fraudulence can be easily recognized.
