PROBLEM TO BE SOLVED: To provide a game machine capable of securely preventing leakage of electricity from a recording medium processing device side to the game machine side and preventing inflow of surge voltage to the game machine. SOLUTION: An earth board 1000 has a connector CN1 for connecting one external connection earth to be connected to the outside of the game machine (e.g. a game machine island) to be grounded; a connector CN2 for connecting one FG harness to be connected to the body of the game machine; and a connector CN3 for connecting two earth board harnesses to be connected to a connection terminal board of a game ball dispensing device, etc. On the earth board 1000, a wire 1001 from the connector CN1 and a wire 1002 from the connector CN2 are connected at a connection point, two wires 1003 and 1004 from the connector CN3 are connected at a connection point. The connection point of the wires 1001 and 1002 and the connection point of the wires 1003 and 1004 are connected with a wire 1005, and a surge absorber is disposed on the wire 1002.
