PROBLEM TO BE SOLVED: To provide a game machine capable of making the thin transparent plate of a game board uniformly perform surface light emission. SOLUTION: The game board 30 having a game area in which a game ball is hit includes: plywood 420 where nails for changing the actions of the game balls flowing down on the game area are hit and fixed to the front surface; and a light transmissive transparent resin plate 400 which is superposed on the front surface of the plywood 420 so as to cover at least the game area of the plywood 420. The transparent resin plate 400 includes through-holes 409 at the prescribed positions of the game area. A light incident part 450 for making light be incident on the inner wall of the through-hole 409 in the transparent resin plate 400 is included. Thus, the light is made incident not only from the outer peripheral side surface of the transparent resin plate 400 (e.g. a thin transparent plate) but also from the inner wall of the through-hole 409 of the transparent resin plate 400, unevenness in brightness and darkness is reduced in the transparent resin plate 400, and the surface light emission is uniformly performed in the transparent resin plate 400.
