Abstract:
A golf ball according to the present invention includes a spherical core, a cover member including at least one layer that covers the core, and at least one coating layer that covers the cover member constituting an outermost layer. A plurality of dimples are formed in the cover member constituting the outermost layer. Roughness is formed on the surface of the coating layer. A maximum height Rz and an arithmetic average roughness Ra of the surface of the coating layer satisfy a relationship Rz≥Ra×6.0. The coating layer contains a lustrous material.
