A copper-iron co-fired inductor and its preparation method are disclosed. The copper-iron co-fired inductor comprises: a square magnetic core, the surface of which is covered with an insulating layer; two flat copper wires, which are arranged parallel to each other on the surface of the magnetic core covered with the insulating layer and adhere to three adjacent faces of the square magnetic core, with the ends of the flat copper wires extending to adhere to a fourth face of the square magnetic core; and a shielding layer, which is adhered to the three surfaces of the square magnetic core with the flat copper wires attached, and is pressed together with the square magnetic core, the insulating layer, and the flat copper wires to form an integrated blank. The blank is then co-fired and sintered to form the copper-iron co-fired inductor. The present invention also provides a method for preparing the copper-iron co-fired inductor. The copper-iron co-fired inductor of the present invention, through the design of the aluminum nitride insulating layer, parallel flat copper wires, and iron-silicon-aluminum shielding layer, greatly improves heat dissipation performance.
