A metallic complex yarn having a covering thread is provided to express multiple colors by preparing covering thread for the surface of the metallic yarn, and to raise durability and color reflection effect, and to have the wide range of applications. An aluminum or a silver powder is evaporated on the surface of a polyester film(10) for forming a metal layer. The evaporated polyester film is cut to have established thickness for forming a metallic complex yarn(100). A covering thread(50) consists of the polyester thread dyed on the surface of the metallic complex yarn. The processed covering thread is wound at established intervals to be the metallic complex yarn(500) having covering thread. The exposed area of the metal layer(20) of the metallic complex yarn having covering thread is adjusted by controlling the intervals of the covering thread wound around the metallic complex yarn. The metallic complex yarn having covering thread is formed by winding the two covering threads in the opposite direction around the metallic complex yarn respectively.
