Methods and apparatus are provided to further facilitate detection not only of a position on a position detector pointed to by a pointing member, but also of information other than the position information such as pen pressure applied to the pointing member, in a position detection apparatus of the electrostatic coupling type. In one embodiment, a pointing member includes a first electrode substantially in the form of a rod, a substantially cylindrical second electrode disposed in such a manner as to surround the first electrode, and a transmission signal production section for producing a signal of a first frequency f1 and another signal of a second frequency f2 different from the first frequency f1 and controlling a phase difference between the signals in response to pressure applied to the pointing member. On a position detector side, the signal of the first frequency f1 is used for position detection of the pointing member, and the phase difference is used for detection of information other than the position information such as pen pressure on the pointing member. Alternatively, a pulse signal having a pulse width corresponding to pressure applied to the pointing member is produced, and on the position detector side, the position, pen pressure and so forth are detected from the pulse signal and the pulse width.
