Zusammenfassung:	The purpose of the present invention is to improve the season cracking resistance of a metallic zipper member of which the base material comprises a zinc-containing copper alloy. A metallic zipper member of which the base material comprises a zinc-containing copper alloy and of which the surface underegoes an anti-corrosive treatment, said metallic zipper member having such a property that, when the metallic zipper member is analyzed with a scanning X-ray photoelectron spectroscopic analyzer, the maximum value of the Mn atom concentration is detected at a depth within 100 nm from the surface.
