PROBLEM TO BE SOLVED: To provide an aluminum alloy sheet excellent in adhesion durability, wherein interfacial peeling at a bonding interface of an adhesive is hardly generated even when being exposed to a high-temperature and highly-wet environment, and thereby adhesion strength is hardly lowered; to provide a joined body using the aluminum alloy sheet; and to provide an automobile member.SOLUTION: The aluminum alloy sheet 10 includes an aluminum alloy substrate 1 and a surface oxidized film 2 formed on the surface of the aluminum alloy substrate 1. In the surface oxidized film 2, the amount of zirconium is 0.01-10 atom%, and the amount of magnesium is ≥0.1 and <10 atom%. |
