Abstract
The invention provides a game ball, useful for children's safety, which can be detected far enough away a distance by a vehicle-onboard radar. The invention provides a game ball wherein a reflector memberis disposed within a spherical shell, the diagonal distance of the reflector member coincides with the inner diameter of the spherical shell, the reflector member has a shape constructed by combining three regular polygon platesA,B,C, the center angle of one side thereof being an integral submultiple of 90°, in such a manner that the centers of the three regular polygon plates are coincident and that the three regular polygon plates are perpendicular to each other, and a surface of said reflector memberis imparted with electromagnetic wave reflectivity.
