Abstract
In a golf ball having a surface divided by triangular concave sectors, an area of a surface of a sphere is divided into a plurality of areas forming spherical polyhedron and a plurality of dimples are formed for each of the plurality of areas. A triangular concave sector is formed by continuously forming a plurality of triangular concave on each arc along great circles dividing the surface of the sphere into the plurality of areas. A planar shape of each of the plurality of triangular concave is a triangle and the bases of the triangular concaves are arranged on the arc along the great circles. Peaks of adjacent triangular concaves are located at opposite sides with respect to the arc along the great circles.
