An electronic pen is configured to transmit and receive a signal to and from a position detection sensor by electromagnetic induction. The electronic pen includes a coil and a magnetic core around which the coil is wound. The magnetic core has a through-hole in an axial center direction. The electronic pen includes a capacitor that forms a resonant circuit with the coil. The electronic pen includes a central rod that is inserted in the through-hole of the magnetic core. The central rod has a magnet part and a yoke part that holds the magnet part at a pen tip part of the central rod.
