PROBLEM TO BE SOLVED: To provide a pachinko machine applied with antistatic treatment. SOLUTION: A control circuit base board 2 for controlling the pachinko machine is provided with a first ground wire 4 used as a ground wire for circuit parts 11a and 11b and second ground wires 3 electrically insulated from the first ground wire 4 and having a plurality of holes 7a, 7b, 7c, and 7d. The second ground wires 3 are arranged on both faces of the control circuit base board 2 and brought into conduction when the control circuit base board 2 and a circuit base board case 1a and 1b housing the control base board 2 are locked together. The second ground wires 3 are arranged all around the first ground wire and the first ground wire 4 and the second ground wires 3 are connected together on the outside of the control circuit base board 2 so that the second ground wires 3 protect the first ground wire 4 arranged on the control circuit base board 2 by discharging electric charge when electric charge accumulated inside the pachinko machine is discharged, and prevent erroneous operation of the control circuit and breakage of an element.
