Patent ID: 8587537

Claim:
An electrostatic capacitance-type position detector capable of detecting a position indicated by a finger, comprising: a conductor pattern, in which a plurality of conductors are disposed in a first direction, and a plurality of conductors are disposed in a second direction intersecting with the first direction; a transmission signal supplying circuit for supplying a transmission signal to said plurality of conductors disposed in the first direction; and a differentially amplifying circuit having first and second input terminals for differentially amplifying signals inputted thereto through said first and second input terminals, respectively, the differentially amplifying circuit being configured to receive signals from at least three conductors located close to one another among said plurality of conductors disposed in the second direction, to thereby receive signals from the conductors located on both end sides of the at least three conductors via said first input terminal and to receive a signal(s) from the conductor(s), which is(are) located between said conductors located on both end sides of the at least three conductors, via said second input terminal.
