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.

Abstract: Disclosed herein is a pen pressure detecting module housed in a position indicator, the position indicator having a pen shape and being capable of detecting a pressure applied to a tip portion of the position indicator. The pen pressure detecting module includes a pressure sensing device, a first holder, and a second holder. The pressure sensing device senses the pressure based on a change in a capacitance formed between a first electrode and a second electrode disposed so as to be opposed to each other, which capacitance changes so as to correspond to the pressure that is transmitted to the first electrode. The second holder is housed in the first holder, and the pressure sensing device is disposed so as to sense the pressure applied to the second holder. An engaging portion engaged with a pressure transmitting member that transmits the pressure is formed in the second holder.
