Abstract:
1. A golf ball comprising, on a surface thereof, a plurality of circular dimples, a plurality of non-circular dimples, and a land area which is a non-dimple region composed of a plurality of arcuate first lands, each formed along an edge of one of the circular dimples, and a plurality of second lands, each arranged so as to bridge between two neighboring circular dimples and having a shape that is recessed at a center portion thereof, wherein the non circular dimples have an edge shape defined by a plurality of the first lands in combination with a plurality of the second lands, wherein the shape of the non-circular dimples is configured such that when a virtual triangle is drawn such that each of the vertexes of the virtual triangle are placed inside each of mutually neighboring three circular dimples respectively, of the circular dimple edge within around the vertexes of the virtual triangle define the first land, together with an arc of the non-circular dimple formed opposite the edge of the circular dimple, and rectilinear or curve lines which connect an edge of one arc with an edge of another arc define a second land between adjacent non-circular dimples and are formed so as to bulge outwardly beyond the middle point of each side of the virtual triangle.
