TOUCH PANEL INPUT DEVICE
First Claim
1. A touch panel input device in which, in response to an approaching finger, electrostatic capacitance between each of a plurality of sensor electrodes and the finger varies, the input device comprising:
- a plurality of sensor electrodes disposed planarly in spaced relation; and
a nonconductive member to be placed on the sensor electrodes, the nonconductive member including;
a plurality of first blocks adapted to contact with at least associated central parts of the sensor electrodes; and
a plurality of second blocks provided between the first blocks,wherein the second blocks have a lower permittivity than that of the first blocks.

Abstract
In a touch panel input device of the invention, in response to an approaching finger, electrostatic capacitance between each of a plurality of sensor electrodes and the finger varies, and the input device includes a plurality of sensor electrodes disposed planarly in spaced relation, and a nonconductive member to be placed on the sensor electrodes. The nonconductive member includes a plurality of first blocks adapted to contact with at least associated central parts of the sensor electrodes, and a plurality of second blocks provided between the first blocks. The second blocks have a lower permittivity than that of the first blocks.
