PROBLEM TO BE SOLVED: To provide a game machine including a fraudulence preventing means for preventing fraudulence, etc. by finding a trace of fraudulence. SOLUTION: A board housing case is composed of a plurality of combined case members including: a first case member B having an attaching part 3f on the outer side to which an identification seal LB for identifying a control board unit UN is attached; and a second case member C to be moved relatively to the first case member B when the board housing case is opened/closed. The second case member C has a structure deforming part opposed to the identification seal LB in the direction of movement of the second case member C relative to the first case member B, the deforming part deforming the structure of the identification seal LB. The identification seal LB includes a holding layer 7 in which a number of micro glass beads 5 are arranged in lines and embedded with part of the beads exposed, a printed layer 4 printed on the exposed surface of a number of the glass beads 5, and a reflection layer 6 disposed on the holder layer 7 side to reflect illumination light of prescribed wavelength emitted from the exposed surface of a number of the glass beads 5. The identification seal LB is disposed on a moving region of the structure deforming part according to the movement of the second case member C relative to the first case member B.
