PURPOSE:To draw a metallic extremely fine wire whose diameter is <=30mu by providing a wire extruding and drawing part using a liquid as a pressure medium, and a wire drawing part by a drawing force, in the same pressure vessel, in a working process for drawing a wire by a wire drawing die. CONSTITUTION:A wire to be worked 9 wound in advance to a supply bobbin is made to pass through a wire extruding and drawing die 8c and a wire drawing die 8e, and thereafter, set into a pressure vessel 8. When a liquid pressure medium is pressed in from a hydraulic pipe 6, said wire is extruded from the wire extruding and drawing die 8c, and simultaneously, drawn out of the wire drawing die 8e by a drawing force of a winding machine 13, and wound to a winding reel 12.
