Abstract: An aluminum alloy conductive member for a transport instrument includes: a substrate formed of an aluminum alloy; and a metal oxide coating film that is formed on a surface of the substrate and that includes a metal oxide of an element other than Al. In the aluminum alloy conductive member, the total coating film amount of the metal oxide coating film is 0.1 to 40 mg/m2 in terms of metal equivalent mass, and a constituent of the metal oxide coating film includes an oxide of one or more selected from the element group X consisting of Ti, Zr, Hf, V, Nb, Ta, Mo, and W, and an oxide of one or more selected from the element group Y consisting of Zn, In, Mg, Sn, and Ca.
