PROBLEM TO BE SOLVED: To provide a conductor of Al alloy superior in electrical characteristics and corrosion resistance, without reducing creep resistance to less than that of steel at a high temperature caused due to fastening of a bolt. SOLUTION: This conductor is made of an Al alloy containing 3-0.8% (wt.% and it is applicable to those in the following) of Si, 0.35-1.0% of Mg. one kind or at least two kinds selected from among 0.1-0.6% of Fe, 0.02-0.1% of Cu and 0.01-0.08% of Mn, and its remaining part comprises Al and unavoidable impurities. Its refining is a T6 material, a T8 material or a T5 material. It has a Ni plated coating with a thickness of 3-10μm as a first layer on its surface, and has a Sn plated coating with a thickness of 2-10μm.
