To enable the manufacture of a copper wire excellent in the workability of cold wire-drawing and the surface quality by preventing the accumulation of foreign matter such as dusts and copper powder on the periphery of the inlet of a wire-drawing die.

Wire drawing is performed while jetting a liquid lubricant 7 at high pressure to the vicinity of the inlet of the wire-drawing die 3 when manufacturing a copper drawn wire 5 having a desired diameter by continuously cold-drawing a copper wire 1.
