Abstract
The present invention provides a golf ball in which at least one intermediate layer is formed between a core and a cover, wherein an L value (brightness) of the core is not more than 85 in a Lab display based on JIS Z 8722, an L value (brightness) of a sphere (intermediate layer-encased sphere) obtained by encasing the core with the intermediate layer is at least 75 in the Lab display based on JIS Z 8722, a total light transmittance of the intermediate layer at a thickness of 1.0 mm is 1 to 50%, and a color difference ΔE between the core and the intermediate layer-encased sphere is at least 10.
