摘要： The invention provides a multi-piece solid golf ball composed of a solid core encased by a cover of one or more layer, which solid core has an inner core layer and an outer core layer. The inner core layer is formed primarily of a specific, highly neutralized, ionomeric resin composition, has a diameter of from 10 to 38 mm, and has a cross-sectional hardness difference of within ±5 between any two points on a cross-section formed by cutting the inner core layer in half. The outer core layer is formed of a rubber composition made primarily of polybutadiene rubber. The solid core has a diameter of from 30 to 42 mm. The sum of the respective hardnesses at the center of the inner core layer, at the outer core layer 1 mm outside a boundary between the inner core layer and the outer core layer, at the inner core layer 1 mm inside the boundary, and at the surface of the outer core layer is set to a value in a range of from 260 to 360. Such a golf ball is able to achieve an increased distance.

摘要： A multi-piece solid golf ball composed of a solid core having an inner core layer and an outer core layer encased by a cover including at least an inner cover layer and an outer cover layer. The inner core layer has a JIS-C cross-sectional hardness of from 60 to 83 at any single point on a cross-section, and has a cross-sectional hardness difference between any two points on the cross-section of within ±5. The ball has specific relationships between the hardness of the inner core layer 1 mm inside a boundary between the inner core layer and the outer core layer, the hardness of the outer core layer 1 mm outside the boundary, and the surface hardness of the outer core layer. And, the difference in Shore D hardness between the inner cover layer and the outer cover layer is within ±5.
