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.

A covered electric wire comprises an insulating coating layer on the outer side of a conductor. The conductor comprises a copper alloy consisting of: not less than 0.05% by mass and not more than 2.0% by mass of Fe; not less than 0.02% by mass and not more than 1.0% by mass of Ti; not less than 0% by mass and not more than 0.6% by mass of Mg; and the balance being Cu and impurities. The covered electric wire is a stranded wire comprising a plurality of copper alloy wires stranded together. The plurality of copper alloy wires each have a work hardening coefficient of not less than 0.1 and a wire diameter of not more than 0.5 mm.
