PURPOSE: A fabrication method of drawing wire for electric/electronic parts is provided to be compacted and prevent from peeling of an extruded insulation layer from a thin copper plate, thereby enhancing productivity and preventing from degrading of resistance in bent or curved portion. CONSTITUTION: A fabrication method of drawing wire for electric/electronic parts comprises: a heat treatment step(12) treating a thin copper plate(20); a tin coating step(13) coating tin on the thin copper plate(20); a thin copper plate cutting step(11) cutting the tin coated plate(20) into a desired width; and an extrusion step(16) extruding the cut plate(20) and insulation material using an extruder.
