Abstract
A golf ball that plural kinds of dimples are disposed on a spherical face, and a great circle zone not including even a part of the dimples are formed on the spherical face. An imaginary great circle line is drawn on the great circle zone, and two intersections of the spherical face and a straight line, which is at right angles with a circular plane of which circumference is the imaginary great circle line, and goes through the center of the golf ball, are poles. And, in a ball hemispherical face of which border is the imaginary great circle line, when the spherical face is equally divided with imaginary arc lines which start from the pole and are at right angles with the imaginary great circle line, dimple dispositions of adjacent divided areas sharing an imaginary arc line are not line-symmetric with respect to the imaginary arc line, and the dimple dispositions of the divided areas are rotation-symmetric with respect to the straight line.
