Based on a pulse drive resonance current that flows from a drive signal input unit 13 to Y-axis loop coils Y1, Y2, . . . , YM, a tuned resonance current flows through a position specifying tool 5 that is positioned adjacent to one Y-axis loop coil.

As a result, a position detection output signal S6, which indicates a coordinate position where the position specifying tool 5 is positioned, is obtained. In this manner, by using a simple configuration that uses resonance operations of each component, from a specific positioned target coordinate position, it is possible to obtain a position detection signal that is clearly distinguishable from other coordinate positions.
