A position indicator that electrostatically interacts with a sensor includes: a casing having a pen shape; a conductive core body including a pen tip that protrudes from an opening on one end in the axial direction of the casing; a conductor surrounding the core body; a signal transmitting circuit which, in operation, generates a signal that electrostatically interacts with the sensor, and supplies the generated signal to the core body; and a control circuit which, in operation, produces different electrostatic interactions with the sensor by performing a first control operation that sets the conductor in a state of being grounded while the signal is sent out from the pen tip of the core body to the sensor, and performing a second control operation that sets the conductor in a state different from the state of being grounded.
