    摘要: The present invention provides a golf ball comprising a core, an intermediate layer covering the core, and a cover covering the intermediate layer, wherein the intermediate layer contains a 3-dimensional shaped metal oxide having at least three needle-shaped parts. Blending the 3-dimensional shaped metal oxide into the intermediate layer enhances the rigidity of the resultant intermediate layer and the hardness thereof. Making use of this property, it is possible to improve the durability, the flight performance and the shot feeling of the golf ball.
