A golf ball 2 has, on a surface thereof, a rugged pattern consisting of a land 10 and a large number of dimples 8. A method for designing the rugged pattern includes the steps of: (1) randomly arranging a large number of generating points on the surface of a phantom sphere; (2) assuming a large number of Voronoi regions on the surface of the phantom sphere based on the generating points; and (3) assigning a land to the vicinity of the contour of each Voronoi region and assigning a dimple to a portion of the surface of the phantom sphere other than the land.
