A manufacturing method of a plated wire rod, the method including: preparing a plated wire rod precursor including a base material that is wire-drawn and that has a linear shape and a plating film that is provided on a surface of the base material, where the base material is made of first metal and the plating film is made of second metal of a different composition from the first metal; obtaining a plated wire rod-intermediate body by performing skin-passing on the plated wire rod precursor using a die; inspecting, after the skin-passing, for presence/absence of a defect in the plated wire rod-intermediate body using an eddy current testing device and a camera inspection device; and obtaining a plated wire rod by removing the defect in the plated wire rod-intermediate body that is detected in the inspecting. |
