    • Golf ball 2 has spherical core 4, and cover 6 provided so as to cover this core 4. The core 4 has spherical center 8, and mid layer 10 provided so as to cover this center 8. The resilience coefficient Ec of the center 8, the resilience coefficient Em of the core 4, and the resilience coefficient Eb of the golf ball 2 satisfy the following formulae (1) and (2): Eb≧Ec≧Em  (1); Eb−Ec≧Ec−Em  (2). The difference (Eb−Ec) between the resilience coefficient Eb and the resilience coefficient Ec is equal to or greater than 0.004. The difference (Ec−Em) between the resilience coefficient Ec and the resilience coefficient Em is equal to or greater than 0.004.
    • 高尔夫球2具有球形芯4和覆盖该芯4的盖6.芯4具有球形中心8,中间层10设置成覆盖该中心8.中心8的弹性系数Ec, 核心4的弹性系数Em和高尔夫球2的弹性系数Eb满足下式(1)和(2):Eb≥Ec≥Em(1); Eb-Ec≧Ec-Em(2)。 弹性系数Eb与弹性系数Ec之间的差(Eb-Ec)等于或大于0.004。 弹性系数Ec和回弹系数Em之间的差(Ec-Em)等于或大于0.004。
