PROBLEM TO BE SOLVED: To enlarge the area for setting function parts of a pachinko machine which are related to the electrical control of the pachinko machine to be mounted on the rear side of the pachinko machine. SOLUTION: The picture frame-like frame 1 of this pachinko machine consists of an outer frame 2 to be attached to a pachinko island in a pachinko arcade and a front frame 3 to be attached to the outer frame 2 so that it can be opened/closed in a single swing. A rear side mechanical board 4 is attached to the front frame 3, and a premium ball tank 5, an outer terminal board 6 for the frame, a sound relay board 7, a display lamp relay substrate 8 and a premium ball supplying relay substrate 9 are attached to the rear mechanical board 4. The width W1 of the premium ball tank 5 is about 1/2 of that of the game board 10 (W1=W2.1/2). The game board 10 is attached to the front frame 3, and a data terminal board 11 for the game board attached to the rear side of the game board 10 protrudes from a through-hole 12 formed on the rear mechanical board 4.
