Abstract
A golf ballincludes a main bodyand a paint layerpositioned outside the main body. The main bodyincludes a spherical core, a mid layerpositioned outside the core, and a coverpositioned outside the mid layer. An indentation depth, measured when the paint layerin a cross-section along a plane passing through a central point of the golf ballis pressed by a force of 30 mgf in a direction perpendicular to the cross-section, is not less than 300 nm and not greater than 3000 nm. The paint layerpreferably has a thickness of not less than 5 μm and not greater than 50 μm.
