The present invention provides a golf ball including a plurality of dimples and a land portion surrounded by the plurality of dimples. The land portion includes a large number of land portion pieces. One land portion piece has a shape having at least three vertexes. The land portion includes a land portion piece having a specific shape formed by connecting the land portion piece substantially in point contact with another adjacent land portion piece at each of the vertexes. Further, an outer peripheral edge of the land portion piece having the specific shape includes a plurality of edge elements. A ratio of the number of land portion pieces having a unique shape in which all the edge elements are formed with a predetermined curve is adjusted to a predetermined range of the number of all the land portion pieces constituting the land portion.
