    摘要: A golf ball includes a core, and a cover made from a cover material containing an ionomer resin and also barium sulfate and titanium dioxide added in a total amount ranging from 10 to 25 parts by mass on the basis of 100 parts by mass of the ionomer resin. A flexural amount of the core, measured by applying a load of 980 N thereto, is in a range of 4.0 to 5.5 mm. A ratio of a melt-flow rate to a specific gravity (melt-flow rate/specific gravity) of the cover material is in a range of 1.6 or more. A Shore D hardness of the cover is in a range of 55 to 65.

    摘要: A golf ball includes a solid core and a cover of at least one layer; wherein each of a specific gravity of the solid core and a specific gravity of the cover is nearly equal to a value (S) of a relation expression given by S=W/[(&pgr;/6)×D3], where W is a weight of the golf ball and D is a diameter of the golf ball. The golf ball can enhance the durability to increase the carry of the ball with less variations in carry of the ball.

    摘要: A golf ball includes a core and a cover made from a cover material mainly containing an ionomer resin and also an inorganic filler having a specific gravity of 3.50 or more in an amount of 10 to 25 parts by mass on the basis of 100 parts by mass of the ionomer resin. A flexural amount of the core, measured by applying a load of 980 N thereto, is in a range of 4.7 to 5.3 mm. A specific gravity of the cover material is in a range of 1.050 to 1.100, a thickness of the cover is in a range of 1.5 to 2.0 mm, and a Shore D hardness of the cover is in a range of 57 to 63. A weight of the golf ball is in a range of 45.0 to 46.0 g, and a flexural amount of the golf ball, measured by applying a load of 980 N thereto, is in a range of 3.7 to 4.3 mm. A weight (W) of the golf ball and an inertia moment (MI) thereof satisfy a relationship of 1.53×W+13.32≦MI≦1.61×W+11.02. Such a golf ball can enhance the resilience to increase the carry of the ball, realize player's feeling of hitting the ball, and improve the durability against cracking.
