Abstract

An input sensor is bonded on the rear surface of an insulating support plate which supports the input sensor. By forming the input sensor to be thin, a device in which an input device having the input sensor is incorporated can be formed very thin.

Claims

1. An electrostatic-capacitance-type coordinate input device comprising an input sensor formed in such a manner that an X electrode layer and a Y electrode layer for detecting electrostatic capacitance are multilayered on a flexible substrate,

wherein said input sensor is bonded on the rear surface of an insulating support plate for supporting said input sensor.

2. An electrostatic-capacitance-type coordinate input device according to claim 1, wherein a recess to which the input sensor is fitted is formed on the rear surface of said support plate at a position where said input sensor is bonded.

3. An electrostatic-capacitance-type coordinate input device according to claim 1, wherein a pointing section for pointing the position of said input sensor is formed in said support plate.
