<p>PROBLEM TO BE SOLVED: To provide a game board, in which game nails are stricken in predetermined directions and at predetermined angles.SOLUTION: A method manufactures a game board including: a game board of a flat tabular wooden plywood formed of a first hard layer made of a hard veneer sheet on the back face; and game nails embedded in a predetermined direction and at an inclination of a predetermined angle in the surface of the game board, and having pointed ends of a generally conical shape converging to the leading ends, and generally columnar shanks formed on the leading end side so that the column-shaped guided portions formed to have the same diameter as that of the base ends of the pointed ends may joint. The method comprises: a guide hole forming step of forming guide holes or the holes, which have the same diameter as that of the guided part, which incline at a predetermined angle in a predetermined direction, and which extend through only a first hard layer, at a position where game nails are to be embedded; and a game nail driving-in step of driving the game nails in the guide holes. At the game nail driving step, the game nails are so guided that the pointed ends and the guided parts are guided along the guide holes so that the driving-in angle and the driving-in direction may be corrected to a predetermined direction and a predetermined angle.</p> |
