ABSTRACT:
An input device, which is small-sized and inexpensive in spite of being simple in construction and thin, comprises at least one primary electrode and a plurality of secondary electrodes, both electrodes being formed in the same plane. A position of a dielectric is identified on the basis of differences in electrostatic capacity between the primary electrode and the secondary electrodes, which electrostatic capacity is changed by the dielectric positioned on a surface side of the both electrodes.
