Abstract

A position detecting sensor is configured by providing a dielectric member having flexibility between first conductors and second conductors and providing spacers for separating the first conductors or the second conductors from the dielectric member by a determined gap. When a pressing force is applied by an indicator (e.g., a finger or a pen) on the position detecting sensor, the first conductor and the second conductor come to abut each other, with the dielectric member interposed therebetween. Further, an abutting area (contact area) between the dielectric member and the conductor changes (e.g., increases) according to the pressing force applied by the indicator. Thus, capacitance of the capacitor formed between the first conductor and the second conductor is largely changed, to allow detection of a position indicated by the indicator as well as the pressing force applied at the indicated position with high sensitivity and high accuracy.
