Claim:
1. A position indicator, which, in operation, capacitively couples with a sensor to indicate a position on the sensor, the position indicator comprising: a pen-shaped body; a transmission signal production circuit which, in operation, transmits a plurality of signals to the sensor; a position indicating tip being conductive and extending from a distal end of the pen-shaped body; and plural electrode pieces provided near the distal end of the pen-shaped body, the plural electrode pieces being electrically separated from each other and arranged to collectively form a columnar shape that surrounds a central axis of the pen-shaped body, the central axis being disposed between at least two of the plural electrode pieces, wherein the position indicating tip and the plural electrode pieces are coupled with the transmission signal production circuit to transmit the plurality of signals to the sensor to indicate angular information of the position indicator.
