Abstract
A position indicator has a pen-like appearance and interacts capacitively with a sensor of a position detection apparatus. The position indicator includes: a housing; a first electrode and a second electrode that are arranged at one end of the housing in an axial center direction thereof, wherein the second electrode encircles the first electrode, and first electrode is partially exposed from the housing in the axial center direction of the housing; and a signal transmission control circuit that supplies at least the first electrode with a first signal, wherein the first electrode outputs the first signal to interact capacitively with the sensor. The signal transmission control circuit is further configured to cause the second electrode to output a second signal that cancels out the first signal output from the first electrode.
