Golf ball 1 has a core 2 and a cover 3. The core 2 is composed of a center 4 and a mid layer 5. Numerous dimples 6 are formed on the surface of the cover 3. Base polymer of the cover 3 includes a mixture of an ionomer resin and a thermoplastic elastomer as a principal component. Shore D hardness of this cover 3 is 55 or greater and 70 or less. A proportion of number of dimples 6 having the tilt angle of from the position, which is 20% downward from the dimple edge in an in-depth direction, down to the position, which is 50% downward from the dimple edge, of 65 or greater and 85 or less occupied in total number of dimples is equal to or greater than 20%.
