PROBLEM TO BE SOLVED: To provide an extra-fine plated wire manufacturing method capable of efficiently manufacturing an extra-fine plated wire by suppressing generation of metal powder attributable to a plating layer. SOLUTION: In the extra-fine plated wire manufacturing method in which a plated copper or copper alloy wire is drawn by a die 10, the wire is drawn before the wire diameter reaches≤0.05 mm by setting the die bearing pressure which is the drawing force divided by the contact area of the wire with an inner face of the die to be≤1.47×10<SP>2</SP>MPa, the die angle (2α) to be 6-10°, and the reduction rate of area to be 5-15%, respectively.
