Abstract: A golf ball surface is divided into faces of an icosidodecahedron consisting of 20 regular triangles and 12 regular pentagons, each of said 20 regular triangles is subdivided into 4 small regular triangles, each of said 12 regular pentagons is subdivided into 5 isosceles triangles, 6 dividing lines of the spherical surface occur when structured as above, and on the remaining 5 dividing lines except 1 mold parting line of 6 dividing lines are crossed the dimples, said dimples aren't crossed on the center of said regular triangles and pentagons, and said dimples intervals are arranged in a spaced circle on the basis of on the center of the respective regular triangles and pentagons.
