Abstract
A golf ball includes oval dimples arranged on the surface thereof. Each of the oval dimples has a long diameter DL and a short diameter DS in a planar shape thereof and further having a depth DPL on a first cross section of the oval dimple along the long diameter DL and a depth DPS on a second cross section of the oval dimple along the short diameter DS, the depth DPL being a distance taken on the first cross section along the long diameter DL from a first line connecting both ends of the first cross section of the oval dimple to a deepest point of a dimple bottom surface, the depth DPS being a distance taken on the second cross section along the short diameter DS from a second line connecting both ends of the second cross section of the oval dimple to a deepest point of a dimple bottom surface, a relationship between the depth DPL and the depth DPS being defined as a following formula (1):DPS>DPL  (1). Each of the oval dimples further having a cross-sectional area DLA on the first cross section of the oval dimple along the long diameter DL and a cross-sectional area DSA on the second cross section of the oval dimple along the short diameter DS, the cross-sectional area DLA being surrounded by the first line connecting both ends of the first cross section of the oval dimple and the bottom surface thereof, the cross-sectional area DSA being surrounded by the second line connecting both ends of the second cross section of the oval dimple and the bottom surface thereof, a relationship between the cross-sectional area DLA and the cross-sectional area DSA being defined as a following formula (2):DLA≧DSA  (2).
