Abstract

A position pointer includes a signal generation circuit, which generates at least one signal. The position pointer in operation transmits the at least one signal to a sensor of a position detector. The position pointer includes a first electrode arranged to protrude from one end portion of a pen-shaped housing along an axial center direction and a second electrode including at least three electrode pieces disposed near the first electrode in such a manner as to surround a central axis of the housing. The at least three electrode pieces are electrically isolated from each other. The position pointer has a signal supply control circuit, which, in operation, controls supply of signals to selectively supply the at least one signal to the second electrode that includes the at least three electrode pieces and to the first electrode.
