An object of the present invention is to provide a golf ball traveling a great flight distance. The present invention provides a golf ball comprising a spherical core and a cover covering the spherical core, wherein the golf ball has a ratio (t 2 /t 1 ) of a time (t 2 ) to a time (t 1 ) of 1.05 or more in a hitting test using a driver (at a head speed of 40 m/sec), wherein the time (t 1 ) is a time taken from a moment that the driver begins to contact with the golf ball to a moment that the golf ball reaches a maximum deformation amount, and the time (t 2 ) is a time taken from the moment that the golf ball reaches the maximum deformation amount to a moment that the golf ball leaves the driver. |
