ABSTRACT:
In a golf ball, ridges each extending to define a non-circular shape, typically a polygonal or star shape, delimiting a predetermined area are arranged on its spherical surface in good balance for reducing the air resistance of the ball in flight and thus drastically improving the flight performance.
