PROBLEM TO BE SOLVED: To prevent the surface defects which may be generated in the injection molding of the game board. SOLUTION: The game board 1 has a laminate structure which contains a front plate 40 and a board 30 overlying the rear of the front plate 40. The front plate 40 and the board 30 are joined together by the insert molding in which the front plate 40 is inserted into a mold and a synthetic resin is injected into the mold and formed into the board 30 and hence, the synthetic resin injected (formed into board 30) closely contacts the front plate 40 inserted. This generates little surface defects such as welding on the board 30. The front plate 40 can conceal the defects, if any, thereby making no defect appear on the surface of the game board 1.
