A golf ball comprises a large number of dimples (4) on a surface thereof.
The dimple (4) includes a first curved surface (7) provided from
a position (P2) placed downward by 85% of a depth to a position (P1)
placed downward by 100% of the depth in a direction of the depth from an edge (E)
and a second curved surface (8) provided from a position (P5) placed
downward by 20% of the depth to a position (P3) placed downward by 50% of
the depth in the direction of the depth from the edge (E). A percentage, to a total
number of the dimples, of a number of the dimples in which a ratio (R1/R2)
of a radius of curvature (R1) of the first curved surface (7) to
a radius of curvature (R2) of the second curved surface (8) is 5
to 55 is 20% or more. A third curved surface (9) is present between the
first curved surface (7) and the second curved surface (8). A fourth
curved surface (10) is present between the second curved surface (8)
and the edge (E). A distance (F) between the deepest portion (P2) of the
dimple (4) and a phantom sphere (6) is 0.10 mm to 0.60 mm.
