PROBLEM TO BE SOLVED: To improve the appearance of a game board and to easily and positively fix game pins. SOLUTION: A spiral projecting part 402 brought into pressure contact with the inner peripheral surface of an insertion hole 3a is formed at the outer periphery of an insertion part 401 of the game pin 40 inserted in the insertion hole 3a bored in the board face of the game board 3. The game pin 40 is thereby inserted in the game board 3, with the projecting part 402 screwed in a pressure contact state with the inner peripheral surface of the insertion hole 3a.
