摘要

An upper structure (310) of a female snap fastener (300) comprises a post retaining member (110) for retaining a post (12) of a male snap fastener (10) and a receiving member (210) for receiving the post retaining member (110). The receiving member (210) includes a circumferential wall part (220) that extends in a vertical direction so as to surround the post retaining member (110), a bottom part (230) that is connected to a lower end of the circumferential wall part (220) and is provided inside the circumferential wall part (220), and an outer circumferential part (240) that is connected to an upper end of the circumferential wall part (220) and is provided outside the circumferential wall part (220). An opening (260) is defined by a peripheral edge part (250) between the upper end of the circumferential wall part (220) and the outer circumferential part (240).
