Abstract:
A pointer detection apparatus and a position detection sensor are provided, with which a signal transmission characteristic of a conductor for detecting a position at a periphery of a transparent region (valid area) is improved. Also, a simplified method of manufacturing the position detection sensor is provided. The position detection sensor includes a first glass substrate, a transmission conductor group formed of a plurality of transparent conductors disposed on one face of the first glass substrate, a reception conductor group formed of a plurality of transparent conductors disposed in a direction crossing the transmission conductor group, and a signal detection circuit for detecting a signal generated in the reception conductor group based on the existence of a pointer near the position detection sensor. The position detection sensor further includes a metal wiring line pattern disposed in parallel with the transmission conductor group in a non-transparent region (outside the valid area) so as to reduce resistance of that portion of the transmission conductor group to thereby improve its signal transmission characteristic.
