Abstract
An extra-fine copper alloy twisted wire including a plurality of copper alloy wires with a wire diameter of 0.010 to 0.025 mm twisted together, each of the copper alloy wires including 1 to 3 weight % of silver (Ag) and a balance consisting of a copper and an inevitable impurity, the copper alloy twisted wire further including a tensile strength of not less than 850 MPa, and an electrical conductivity of not less than 85% IACS. The extra-fine copper alloy twisted wire includes a solid insulation with a thickness of not more than 0.07 mm formed on an outer circumference of the extra-fine insulated wire.
