Abstract
An electronic pen includes a magnetic core that has a through-hole and around which a coil is wound in a direction along this through-hole, a core body that is inserted in the through-hole of this magnetic core and has electrical conductivity, a capacitor that forms a resonant circuit with the coil, a signal generation circuit that generates a signal that enables a position of the electronic pen to be detected, which is transmitted through the core body, an electricity storage device, and a charge circuit that charges the electricity storage device by an induced current generated in the coil according to an external magnetic field. While the resonant circuit operates, the signal generated by the signal generation circuit is concurrently transmitted through the core body.
