<p>Disclosed are an electrode wire (2) for electro-discharge machining and a method for manufacturing the same, which reduce micro-particles generated when an electrode wire is subject to the electro-discharge machining and improving the machining speed and the surface roughness of a workpiece. The method includes preparing a wire rod, which includes a first metal (21) and has a first diameter, as a core wire, plating a second metal (23) on the core wire, performing a fine wire process for the core wire plated with the second metal so that the core wire has a second diameter, while forming a corrugation (23a, 24a) having a predetermined pattern on a surface of the core wire having a second diameter, and performing a heat treatment process to form a first alloy layer at a boundary surface between the core wire and the second metal through a mutual diffusion between the core wire and the second metal, and to form a second alloy layer at an outer portion of the first alloy layer through diffusion of the first metal toward the second metal.</p> |
