PROBLEM TO BE SOLVED: To simplify the ground connection of assembling components of a game board of a pachinko machine. SOLUTION: A middle plate sheet metal 24 is mounted at an edge of a middle plate 12 which is mounted on a main body frame of the pachinko machine. A mounting piece part 26a of a leaf spring-shaped sheet metal 26 for ground, which can be deformed elastically, is applied to the sheet metal 24; and the sheet metal 26 is co-tightened with a screw 25 for fixing the sheet metal 24 and fixed to the middle plate 12 (the sheet metal 24), so that the sheet metal 26 and the sheet metal 24 can be electrically connected together. When the game board 13 is mounted on the middle plate 12, a contact piece part 26c of the sheet metal 26 is brought into pressure contact with the backside of an outer rail 20 of the game board 13, so that the sheet metal 26 and the outer rail 20 can be electrically connected together. Thus, the outer rail 20 makes a ground connection via the sheet metal 26 and the sheet metal 24.
