Zusammenfassung:	An improved season cracking resistance of a metallic fastener member is provided and includes a copper alloy containing zinc as a base material. The metallic fastener member includes, as a base material, a copper alloy containing zinc, and the metallic fastener member has a surface to which a rust prevention treatment has been applied and has such a property that, when analyzed by a scanning X-ray photoelectron spectroscopy apparatus, a maximum value of an atomic concentration of Mn is detected at a depth of 100 nm or less from the surface.
