Abstract
An electronic pen has increased strength, especially a pen tip portion that is not bent or broken even if the electronic pen is slimmed down. A core unit includes a ferrite core on which a coil is wound and a core rod. The core rod is fixed from a first end of the ferrite core to a second end of the ferrite core at a position including a center axis of the ferrite core and projects at an end thereof from the first end of the ferrite core. The ferrite core includes a first coil non-winding portion on which the coil is not wound provided on the pen tip side of the ferrite core. In operation, the end of the core rod and part of the first coil non-winding portion of the ferrite core project from an opening of a housing of the electronic pen.
