PROBLEM TO BE SOLVED: To provide a method for firmly joining an aluminum member with a copper member, and a joined structure obtained by using this method. SOLUTION: (1) In this method for joining an aluminum member with a copper member, a metal layer is formed on a joining surface of the copper member, and the metal layer is brazed with a joining surface of the aluminum member. (2) In a joined structure, a metal layer and a brazed layer are provided between the aluminum member and the copper member, and the metal layer is formed on a joining surface of the copper member. (3) In a joined structure, a joining section of an aluminum or aluminum alloy member with a copper or copper alloy member comprises a copper or copper alloy layer, a metal layer formed and remaining on the copper or copper alloy layer, a brazing filler metal, a reaction layer of the metal and aluminum, and an aluminum or aluminum alloy layer.
