PROBLEM TO BE SOLVED: To provide a game machine capable of suppressing fraudulence to a control board. SOLUTION: This game machine is constituted such that a non-contact type micro IC chip 401 is attached to the surface of the projection part 400 of a box base 263A, an upper side is covered with a main board 405, the external antenna 411 of a reader is inserted to the recessed part of the back surface of the box base 263A, and its identification information can not be attained without getting close to the IC chip 401. That is, in the game machine, since the presence can not be easily confirmed just by looking at and confirming the IC chip 400 with naked eyes and simply bringing the reader close to the box base 263A, fraudulent operations and imitation, etc., become difficult, and it is effective for suppressing the fraudulence to the main board 405.
