Abstract
A position detection apparatus including: a sensor including a plurality of first conductors juxtaposed in parallel to each other in a first direction, a plurality of second conductors juxtaposed in parallel to each other in a second direction, and a plurality of third conductors juxtaposed in parallel to each other in a third direction. The first to third conductors are disposed such that a plane defined by the first conductors, another plane defined by the second conductors, and a further plane defined by the third conductors are placed in a superposed relationship with each other. The apparatus further includes a signal processing circuit configured to supply a signal to the sensor and detect a pointed position by a pointer on the sensor based on a signal obtained from the sensor in response to the signal supplied thereto; the signal processing circuit identifying a position actually pointed to by the pointer.
