A snap button is provided, which can function as both of .a male snap and a female snap without accurate alignment or positioning two snap buttons to be engaged with each other. The snap button comprises a button body, wherein the button body includes a plurality of projections and a plurality of recesses, which are circumferentially alternately arranged. Each of the projections includes at least one salient and each of the recesses includes at least one protrusion. Each of the projections may be shaped as a horizontal cross-section thereof gradually decreases from the proximal end to the distal end. Further, the circumferential range of each recess is larger than that of each projection. The protrusion may have one or more cutouts, and the salient may be hemispherically shaped. |
