Abstract
A covered electrical wire comprises a conductor and an insulating covering layer provided outside the conductor, the conductor being a stranded wire composed of a strand of a plurality of copper alloy wires: composed of a copper alloy containing Fe in an amount of 0.2% by mass or more and 1.6% by mass or less, P in an amount of 0.05% by mass or more and 0.4% by mass or less, and Sn in an amount of 0.05% by mass or more and 0.7% by mass or less, with the balance being Cu and impurities, and having a mass ratio of Fe/P of 4.0 or more; and having a wire diameter of 0.5 mm or less.
