To provide a game machine using a game machine board storage box capable of reducing fraudulent unsealing.

The Pachinko machine includes a sealing member 280 for sealing a box base 265 and a box cover 267 in which a main control board 261a is housed inside. Since the box cover 267 has a surrounding wall part 283 to surround a boundary surface BL between the box base 265 and the box cover 267 at a position of the sealing member 280, insertion of a fraudulent slender member into the boundary surface BL can be made difficult, and insertion of the fraudulent slender member into the boundary surface BL to separate the box base 265 from the box cover 267 at the position where the sealing member 280 is present can be made difficult. As a result, the fraudulent unsealing of the board box 263 can be reduced. The Pachinko game machine 10 with the above structure can be provided.
