PROBLEM TO BE SOLVED: To attach/detach a game board part to/from the attaching hole easily and highly efficiently without damaging stopper nails. SOLUTION: This game board part is attached to the game board surface by means of an attaching hole. Flexible arms 15 are formed on the rear side of the part, and a stopper nail 16 to be engaged at a prescribed position of the attaching hole is formed at each flexible arm 15. The stopper nail 16 is to be detachably engaged with the attaching hole 24 at a prescribed position, with the flexible arm 15 flexing. In that case, sliding surfaces 26, 26a are formed at the top of the stopper nail 16 so that the stopper nail 16 can smoothly slide on the inner surface of the attaching hole.
