Abstract:
1. A position indicator for use in conjunction with a position detecting sensor that carries out position detection by detecting a change in capacitance, the position indicator comprising: a first electrode configured to receive an alternating-current (AC) signal from the position detecting sensor; a signal enhancing processing circuit configured to subject the AC signal received via the first electrode to determined signal enhancing processing; and a second electrode different from the first electrode and configured to be supplied with an enhanced signal output from the signal enhancing processing circuit; wherein the first electrode and the second electrode are both disposed at the same end section of the position indicator, wherein the enhanced signal having a determined correlation with the AC signal received via the first electrode from the position detecting sensor is formed while the enhanced signal is sent out to the position detecting sensor via the second electrode, and wherein the signal enhancing processing circuit generates the enhanced signal having a signal level higher than a signal level of the AC signal received via the first electrode.
