Abstract

An object of the present invention is to provide a golf ball exhibiting an excellent shot feeling and resilience, and a constituent material thereof. The present invention provides a golf ball resin composition having a bending stiffness (M) ranging from 300 kgf/cmto 24,000 kgf/cmat a bending angle from 3° to 12°, a ratio (M/M) of the bending stiffness (M) at the bending angle from 3° to 12° to a bending stiffness (M) at a bending angle from 24° to 30° ranging from 0.20 to 2.00, and a slab hardness ranging from 30 to 65 in Shore D hardness.
