To provide a Pachinko game machine, which can be easily found out when having the history of a seal member peeled off.

A seal 100 is stuck to the boundary of a case body 55 and a cover 56, in the left-side surface of a main control board case 57. An RF tag 200 is stuck to the rear face of the seal 100. The rear face of the seal 100 is electrically connected to a peeling detection circuit 67, and when the seal 100 is peeled off, the history is stored in a memory part 67b. If the history of the seal 100 peeled off is stored in the memory part 67b, the power supply to the main control board 50 from a power board 94 is prohibited to prevent a game from being started when the Pachinko game machine 1 is started. Thus, by finding out the Pachinko game machine in which a game is not started, the Pachinko game machine, in which the fraudulent act of peeling off the seal 100 has been performed, can be easily found out.
