摘要： The object of the present invention is to provide a golf ball having a lasting scent. The golf ball of the present invention is a golf ball comprises a paint film on a surface of the golf ball body, wherein the paint film comprises a microcapsule encapsulating a perfume material. Employment of such a structure inhibits a release of the perfume material component in the paint film during storage of a golf ball, since it is included in the microcapsule. When in use, a film material of the microcapsule is gradually broken by hitting the golf ball, so that the perfume material included in the capsule is gradually released.
