PROBLEM TO BE SOLVED: To provide a game machine which can make a transparent thin plate of a game board uniformly plane-emit light.SOLUTION: A game board 30 having a game region into which game balls are driven comprises: plywood 420 into which nails for imparting changes to behaviors of the game balls flowing down in the game region are driven to a front face side; and a light-permeable transparent resin plate 400 which is lapped on the front face side of the plywood 420 so as at least to cover the game region of the plywood 420. Since the transparent resin plate 400 has a penetration hole 409 at a prescribed point of the game region, and a light incident part 450 for making light incident to an inner wall of the penetration hole 409 of the transparent resin plate 400, light is not only made incident from an external peripheral side face of the transparent resin plate 400 (for example, transparent thin plate) but also can be made incident from the inner wall of the penetration hole 409 of the transparent resin plate 400, therefore, the unevenness of brightness at the transparent resin plate 400 can be reduced, and the transparent resin plate 400 can uniformly plane-emit light. |
