The invention discloses a multifunctional component. The multifunctional component comprises a conductive coil, and at least one of a first lamination capacitor, a chip resistor and magnetic beads, wherein the conductive coil, the first lamination capacitor, the chip resistor and the magnetic beads are in mutual electrical insulation; the first lamination capacitor is positioned in the inner side and/or the outer side of the conductive coil; the chip resistor is positioned in the top surface and/or bottom surface of the conductive coil; and the magnetic beads are positioned in the top surface and/or bottom surface of the conductive coil. The multifunctional component realizes functions of multiple kinds of electronic components on one patch device simultaneously, so that the layout space of a PCB (printed circuit board) is reduced, and the PCB routing is shortened and the material is reduced as well.
