1. A method of producing an electrically conductive metal composite yarn having increased yield strength, the method comprising:

  • a first process of producing a covered yarn by wrapping a conductive yarn around a surface of a yarn;

    a second process of producing a twisted covered-yarn by additionally twisting the covered yarn produced through the first process; and

    a third process of producing a reinforced plied-yarn by wrapping a yarn around a surface of multiple strands of the twisted covered-yarn in a covered state to increase yield strength of the conductive yarn.
