Abstract
A golf ball that enhances flight performance is provided. A golf ball according to the present invention includes a spherical core, at least one cover member that covers the core, and a coating layer that covers the cover member configuring the outermost layer. A plurality of dimples are formed in the cover member configuring the outermost layer. The thickness of the coating layer is 5.0 μm or more. Roughness is formed on the surface of the coating layer after coating the cover member configuring the outermost layer. The maximum height Rz and the arithmetic average roughness Ra of the surface of the coating layer satisfy the relationship Rz≧Ra×6.0.
