PROBLEM TO BE SOLVED: To more surely prevent fraudulent modification of a control board housed in a control board housing box. SOLUTION: The box is provided with a case body 1 and a cover body 2 mounted thereon to house a control board 3 in the Pachinko machine. Connection means (40 and 41) are provided to connect the case body 1 and the cover body 2 inseparably. Thus, the connected part by the connection means (40 and 41) must be destroyed for carrying out a fraudulent modification, such as replacement of ROMs, on the control board 3, eventually leaving marks indicating such a destruction clearly.
