Abstract
A copper alloy wire, a copper alloy twisted wire, a covered electric wire, and a wiring harness that have high strength and excellent impact resistance. A copper alloy wire for use as a conductor has a ratio of 0.2% proof stress to tensile strength that is 0.87 or less. A copper alloy twisted wire includes a plurality of the twisted copper alloy wires. A covered electric wire includes a conductor including the copper alloy wire and an insulation cover that covers an outer periphery of the conductor. A wiring harness includes the covered electric wire, and a terminal metal fitting that is attached to the conductor of the covered electric wire.
