    摘要： A golf ball includes a core and a cover. A difference (FB2−FC2) between a secondary natural frequency FB2 of the golf ball and a secondary natural frequency FC2 of the core is not less than 80 Hz and not greater than 420 Hz. The golf ball having a sum (FB2+FC2) of not less than 4000 Hz is preferable. Preferably, the FC2 is not less than 1800 Hz and not greater than 2500 Hz. Preferably, the FB2 is not less than 2000 Hz and not greater than 2800 Hz. Preferably, an amount of compressive deformation Dc is 2.30 mm to 3.90 mm. Preferably, an amount of compressive deformation Db is 1.80 mm to 3.30 mm. Preferably, a thickness Tc is 0.80 mm to 2.10 mm. Preferably, a Shore D hardness Hc is not less than 52 and not greater than 65.

    摘要： An object of the present invention is to provide a golf ball traveling a great distance on driver shots and on iron shots. The present invention provides a golf ball comprising a spherical core including an inner layer and an outer layer, and a cover, wherein a difference (HX+1−HX−1) between a hardness (HX+1) at a point outwardly away in a radial direction from a boundary between the inner layer and the outer layer of the spherical core by 1 mm and a hardness (HX−1) at a point inwardly away in the radial direction from the boundary between the inner layer and the outer layer of the spherical core by 1 mm is 0 or more in Shore C hardness, a surface hardness (HX+Y) of the spherical core is more than 65 in Shore C hardness, an angle α of a hardness gradient of the inner layer is 0° or more, a difference (α−β) between the angle α and an angle β of a hardness gradient of the outer layer is 0° or more, a thickness of the cover is 3 mm or less, a difference (Hc−Hx+y) between a hardness (Hc) of the cover and the surface hardness (HX+Y) of the spherical core is 2 or more in Shore C hardness, and the cover has a highest hardness among the constituent members of the golf ball.
