Provided is a golf ball that has excellent flight performance and feel at impact, and is easy to match with a sense of distance by putting. The golf ball 2 includes a core 4, an inner cover 6, a main cover 8, and an outer cover 10. Radius Rc of the core 4, Shore C hardness Hs of the surface of the core 4, thickness Tm of the main cover 8, Shore C hardness Hm of the main cover 8, thickness Ti of the inner cover 6, Shore C hardness Hi of the inner cover 6, outer cover S = Hs × Rc × 0.05, M = Hm × Tm, I = Hi × Ti, O = Ho × To and Q = (I + O), calculated from the thickness To of 10 and the Shore C hardness Ho of the outer cover 10 / 2 satisfies 15 ≦ MS ≦ 100, 0.25 <Q / M ≦ 0.5 and 30 <IO.
