PROBLEM TO BE SOLVED: To surely protect control components in various control boards and a discharge device from static electricity by surely eliminating the static electricity on the upstream sides leading to the control boards, in a game machine which discharges game balls put out from a tank from the discharge device through a rail. SOLUTION: In a Pachinko game machine 10, a ball tank 72 and a tank rail 73 are molded with a conductive material A having a 10<SP>0</SP>Ωsurface resistance value. Meanwhile, a winning ball/dispensing ball discharge unit 75 is molded with a conductive material B having a larger surface resistance value (10<SP>2</SP>Ω) than the conductive material A, and a case rail 74 is molded with a conductive material C having a larger surface resistance value (10<SP>3.8</SP>Ω) than the conductive material B (10<SP>2</SP>Ω). Thus, the static electricity generated by flow of the game balls B when dispensing the balls and winning a prize is aggressively eliminated in the ball tank 72 and the tank rail 73 on the upstream sides compared with the winning ball/dispensing ball discharge unit 75.
