PROBLEM TO BE SOLVED: To provide a board storage box of a game machine preventing the execution of a fraudulent process to a circuit board stored therein. SOLUTION: The board storage box 150 storing a circuit board 90 is assembled and constituted of a plurality of components including the circuit board 90 such as a box body 51, a transparent plate 64 and a cover body 70; and is provided with a locking projection 57 of the box body 51, or the assembling component for covering the circuit board 90, and a fixing means such as a rivet 59 whose assembled state cannot be released unless breaking a prescribed portion (the base part of a locking suspension piece 76) related to the locking suspension piece 76 of the cover body 70. There is no other method for taking out the circuit board 90 stored in the inside by separating the box body 51 from the cover body 70 except at least breaking the base part of the locking suspension piece 76, and if the base part of the locking suspension piece 76 is broken, this game machine can immediately acquire that the fraudulent process is made.
