Twisting of the plated wires is performed tightly with no gap between the adjacent plated wires so that a plated layer can be interposed. Either a twisted structure or an open twisted structure having a gap such that a plating layer can be interposed in part or all of adjacent plating wires may be used. The plated layer of the plated wire and the plated layer of the outer shell may be made of the same or different materials. Manufacturing of the plated stranded wire of the present invention is as follows in the case of the plated stranded wire of the first aspect of the present invention. First step: plating wire,
The inner shell is formed by twisting into a single layer or multiple layers having a tight twist structure with no gap between adjacent plating wires so that a part of the plating layer or the inner plating layer can be interposed. Second step: the inner shell is immersed in a plating tank, and the plating layer as the outer shell is fused around the inner shell with the plating part of the plating wire forming the uneven envelope surface on the outer circumference of the inner shell. And are integrally formed. And, in the case of the plated stranded wire according to the second aspect of the present invention, it becomes as follows. First step: The plating wire is twisted into a single layer or a multilayer having an open twist structure in which a part or all of the adjacent plating lines have a gap enough to allow a part of the plating layer or the inner plating layer to intervene. An inner shell is formed. Second step: the inner shell is immersed in a plating tank, and the plating layer as the outer shell is fused around the inner shell with the plating part of the plating wire forming the uneven envelope surface on the outer circumference of the inner shell.
