[Problem] To provide a golf ball having exceptional flying distance, approach performance, and hitting sensation. [Solution] This ball (2) is provided with a core (4), a middle layer (6), and a cover (8). The core (4) has an inner core (10) and an outer core (12). The cover (8) has an inner layer cover (10) and an outer layer cover (12). The inner core volume (Vc), the middle layer volume (Vm), the middle layer hardness (Hm), the inner cover volume (Vinc), the inner cover hardness (Hinc), the outer cover volume (Vouc), the outer cover hardness (Houc), and the ball volume (V) satisfy the following relational expressions (a) to (g). (a) Vc/V < 0.07, (b) Hm > Hinc > Houc, (c) Hm – Houc > 25, (d) Vm > Vinc > Vouc, (e) (Vm + Vinc + Vouc)/V < 0.30, (f) Vm/Vouc > 1.50, (g) (Vm • Hm)/(Vouc • Houc) > 3.0 |
