PURPOSE: Provided is a golf ball which includes a reinforcing member to concentrate force beaten at the outer circumference side of the golf ball on a center part for generating strong repulsive power so that it extends flying distance remarkably. CONSTITUTION: The golf ball is characterized by comprising an elastic inner core(10), an elastic outer core(20) and a cover(30) wherein multiple reinforcing members(40) are radially inserted into the elastic outer core from inner circumference side toward outer circumference side. Therefore, all force are concentrated on the inner core to improve flying distance when force is transmitted to the cover.
