    Abstract: An exemplary embodiment of the present invention provides a stylus pen including: a body; a conductive tip configured to be exposed from an inside of the body to an outside thereof; and a resonance circuit connected to the conductive tip to resonate an electrical signal transferred from the conductive tip. An inductor unit of the resonance circuit includes a ferrite core and a coil wound in multiple layers over at least a portion of the ferrite core. The ferrite core includes nickel, and the coil can be formed by a litz wire with adjacent winding layers that are wound to be inclined in a zigzag form.
