Abstract:
A golf ball (2) includes a main body (4) and a paint layer (6) positioned outside the main body (4). The paint layer (6) includes an inner layer (14) and an outer layer (16) positioned outside the inner layer (14). When an indentation depth (nm) is measured on a cross-section along a plane passing through a central point of the golf ball (2) when a force of 30 mgf is applied to the cross-section in a direction perpendicular to the cross-section, an indentation depth Di on a cross-section of the inner layer (14) is smaller than an indentation depth Do on a cross-section of the outer layer (16). A thickness To of the outer layer (16) is smaller than a thickness Ti of the inner layer (14).
