<p>The golf ball is provided with multiple first dimples (1) formed on the surface and multiple second dimples (2), which are formed on the surface around the multiple first dimples (1) and have a diameter smaller than the multiple first dimples (1). The ratio of the depth to the diameter for each of the multiple second dimples is 0.050 or more, and the ratio of the diameter of each of the multiple second dimples (2) with respect to the largest diameter (D1) of the multiple first dimples (1) is 0.21 to 0.41. It is thereby possible to obtain a golf ball with which extreme decreases in lift coefficient in the low speed range can be limited while improving lift coefficient in all speed ranges.</p> |
