摘要： PROBLEM TO BE SOLVED: To provide an aluminum alloy wire excellent in corrosion resistance, to provide an aluminum alloy stranded wire, to provide an insulated wire in which the aluminum alloy stranded wire is used as a conductor, and to provide an electric wire with a terminal equipped with the insulated wire. SOLUTION: This aluminum alloy wire is used for a conductor of the electric wire for an automobile, has 8 mm 2 or less of a cross-sectional area and has a covered layer on the outer face of the end part of the alloy wire on which terminal members composed of copper or copper alloy are mounted. The outermost layer of the covered layer is constituted of tin or tin alloy. In the aluminum alloy wire having 8 mm 2 or less of the cross-sectional area, since an exposed area of the copper or the copper alloy against the exposed area of the aluminum alloy becomes larger in the vicinity of the terminal members composed of the copper or the copper alloy, an electric corrosion is apt to be generated. However, since the tin or the tin alloy exists between the terminal members composed of the aluminum alloy and the copper or the copper alloy, the electric corrosion between the aluminum alloy and the terminal members can be reduced.
