Abstract
A female snap button detachably receives a projection of a male snap button in a projection-receiving space. The female snap button includes an annular protrusion rising from a base and defining the projection-receiving space. In the annular protrusion, there are formed thick-walled portions with the thickness from the inner surface of the protrusion to the radially outer side being relatively thick and thin-walled portions with the thickness being thinner than that in the thick-walled portions. The thick-walled portions and the thin-walled portions are arranged alternately in the circumferential direction.
