1. A position indicator comprising: a tubular core member formed by combining a substantially bar-like first magnetic core and a substantially bar-like second magnetic core such that they face each other in a transversal direction thereof to form a through-hole therebetween; a first coil wound around the tubular core member; a second coil wound around the second magnetic core; a substantially bar-like rod inserted into the through-hole of the tubular core member and adapted to indicate a position of the position indicator; a pen-pressure detecting element for detecting a pressure applied to an end of the rod; a capacitor connected to the first coil to form a resonant circuit; and a switch for controlling “on” and “off” states of the second coil.
