ELECTRONIC PEN AND HANDWRITING INPUT APPARATUS

Disclosed is an electronic pen including a casing having openings, a coil, a magnetic core having the coil wound therearound, and having a through hole extending in an axial direction of the electronic pen, a capacitor that forms a resonant circuit together with the coil, and a core body inserted through the through hole of the magnetic core. The electronic pen exchanges a signal having a frequency corresponding to a resonance frequency of the resonant circuit with a position detection sensor through electromagnetic inductive coupling. The core body includes a pen point portion and a tail portion forming magnetic poles on opposite sides, the pen point portion protruding outwardly from one of the openings of the casing of the electronic pen and being located away from an end of the magnetic core on a pen-point side in the axial direction of the electronic pen.
