Abstract
A golf ballhas a large number of dimplesand a land. A rugged pattern is formed on the surface of the golf ballby these dimplesand the land. These dimplesare arranged in a random manner. Each dimplehas a crater shape. For designing the rugged pattern, a Cellular Automaton method is used. A fluctuation range Rh of the golf ballthat is an index indicating the aerodynamic characteristic during PH rotation is 1.9 mm or less. A fluctuation range Ro of the golf ballthat is an index indicating the aerodynamic characteristic during POP rotation is 1.9 mm or less. The absolute value of the difference dR between the fluctuation range Ro and the fluctuation range Rh is 0.4 mm or less.
