A golf ball containing a core, a reinforcing layer and a cover. The core is formed by a center and a mid layer. The center is formed by a center inner sphere and a center outer layer. The center inner sphere and the center outer layer are obtained through crosslinking of a rubber composition. The base polymer of the mid layer is an ionomer resin. The base polymer of the cover is a thermoplastic polyurethane elastomer. The thickness Tc of the cover is equal to or less than 1.0 mm. The hardness Hc of the cover is 20 or greater and 50 or less. The ratio (D2/D3) of the amount of compressive deformation D2 of the core to the amount of compressive deformation D3 of the golf ball is 0.98 or greater and 1.10 or less.
