Beschreibung
Zusammenfassung:Provided is an electronic pen which communicates with a position detection sensor through electromagnetic induction, including a coil, a columnar magnetic core including a through hole in an axial direction of the magnetic core, a capacitor constituting a resonant circuit together with the coil, and a rod-shaped core body inserted through the through hole of the magnetic core, in which the magnetic core includes a front portion, a back portion, and a middle portion interposed between the front portion and the back portion, an outside diameter of the middle portion is smaller than an outside diameter of the front portion of the magnetic core and an outside diameter of the back portion of the magnetic core, and the coil is wound around the middle portion of the magnetic core.
