Abstract:
In a golf ball having a two-layer core consisting of an inner core layer and an outer core layer and a cover of one or more layer, the inner core layer and outer core layer are each formed of a rubber composition made up primarily of a base rubber, the inner core layer has a diameter of not more than 30 mm; and the core has specific hardness ratios (JIS-C hardness/Shore D hardness) at specific points on the cross-section thereof. This golf ball has a reduced spin rate on full shots with a driver and middle irons, thus imparting to an excellent flight performance, and moreover has a good controllability in the short game on approach shots, making it ideal as a golf ball for professional golfers and mid- and high-level amateur golfers.

Claim (Index 11):
The golf ball of  claim 1 , wherein the outermost layer of the cover has numerous dimples formed on a surface thereof, the ball has arranged thereon at least one dimple with a cross-sectional shape that is described by a curved line or a combination of straight and curved lines and is specified by steps (i) to (iv) below, and the total number of dimples is from 250 to 380:\n (i) letting the foot of a perpendicular drawn from a deepest point of the dimple to an imaginary plane defined by a peripheral edge of the dimple be the dimple center and a straight line that passes through the dimple center and any one point on the edge of the dimple be the reference line: (ii) dividing a segment of the reference line from the dimple edge to the dimple center into at least 100 points and computing the distance ratio for each point when the distance from the dimple edge to the dimple center is set to 100%: (iii) computing the dimple depth ratio at every 20% from 0 to 100% of the distance from the dimple edge to the dimple center; and (iv) at the depth ratios in dimple regions 20 to 100% of the distance from the dimple edge to the dimple center, determining the change in depth \u0394H every 20% of said distance and designing a dimple cross-sectional shape such that the change \u0394H is at least 6% and not more than 24% in all regions corresponding to from 20 to 100% of said distance.
