Zusammenfassung:	The present disclosure provides a method for manufacturing an aluminum alloy member capable of suppressing deterioration in ductility thereof. In the method for manufacturing an aluminum alloy member, an aluminum alloy casting material that contains 2.0 to 5.5 mass % of Cu, and 4.0 to 7.0 mass % of Si in which a content of Mg is 0.5 mass % or less, a content of Zn is 1.0 mass % or less, a content of Fe is 1.0 mass % or less, a content of Mn is 0.5 mass % or less and the balance is made of Al and inevitable impurities is used. The method for manufacturing an aluminum alloy member includes a heating and holding step of heating and holding the aluminum alloy casting material within a solid-liquid coexisting temperature region; and a quenching step of rapidly cooling the aluminum alloy casting material after performing the heating and holding step.
