摘要： The invention provides a golf ball having a solid core, a cover of at least one layer, and a plurality of dimples on a surface of an outermost layer of the cover. The dimples have a volume ratio (VR) of from 1.0 to 1.4%. The ball has an initial velocity, as measured using an initial velocity measuring apparatus of the same type as a USGA drum rotation-type initial velocity instrument, of from 75.5 to 77.7 m/s, and a ratio of total distance traveled when struck at a head speed of 54 m/s to total distance traveled when struck at a head speed of 35 m/s (HS54/HS35) of from 1.30 to 1.50. This golf ball is able to substantially reduce the distance traveled by the ball when struck at a high head speed, while at the same time holding down the decrease in distance when struck at a low head speed.

摘要： The invention provides a multi-piece solid golf ball composed of a solid core encased by a cover of one or more layer, which solid core has an inner core layer and an outer core layer. The inner core layer is formed primarily of a specific, highly neutralized, ionomeric resin composition, has a diameter of from 10 to 38 mm, and has a cross-sectional hardness difference of within ±5 between any two points on a cross-section formed by cutting the inner core layer in half. The outer core layer is formed of a rubber composition made primarily of polybutadiene rubber. The solid core has a diameter of from 30 to 42 mm. The sum of the respective hardnesses at the center of the inner core layer, at the outer core layer 1 mm outside a boundary between the inner core layer and the outer core layer, at the inner core layer 1 mm inside the boundary, and at the surface of the outer core layer is set to a value in a range of from 260 to 360. Such a golf ball is able to achieve an increased distance.
