A golf ball. A cross-sectional shape of each of dimples (8) of the golf ball (2) is a wave-like curve. The wave-like curve has two first curves (14), two second curves (16), two third curves (18), and one fourth curve (20). Each first curve (14) and each third curve (18) are upwardly convex. Each second curve (16) and the fourth curve (20) are downwardly convex. Each first curve (14) is connoted to a land (10) at an edge Ed. Each second curve (16) is connected to the first curve (14) at a first inflexion point (22). Each third curve (18) is connected to the second curve (16) at a second inflexion point (24). The fourth curve (20) is connected to the third curves (18) at third inflexion points (26). In the wave-like curve, the upwardly convex curves (14) and (18) and the downwardly convex curves (16) and (20) are alternately arranged.
