Abstract
The present invention provides a three-piece golf ball which has an improved controllability at an approach shot while maintaining a long flight distance inherent to a solid golf ball. In the three-piece golf ball, the hardness, the specific gravity, and deformation amounts of the center and the core are determined in consideration of the relationship between each other.
