PURPOSE: To produce a soft-magnetic iron electrodeposited coating having respectively specified coercive force and average crystalline grain size in a short time. CONSTITUTION: An iron coated copper wire, to which iron coating of <=2μm thickness is applied by electroplating, is passed through an electric furnace filled with high temp. gaseous nitrogen and heat-treated at 500-800 deg.C temp. of iron coating for 1-10sec, by which a soft-magnetic iron coated copper wire is produced. By this method, the soft-magnetic iron coated wire, coated with the soft-magnetic iron electrodeposited coating having <=400e coercive force and <=500Åaverage crystalline grain size, can be produced in a short time.
