ABSTRACT:
A coordinate input apparatus has a film sensor substrate. An X electrode array having a plurality of electrodes in parallel to each other is disposed on the obverse surface of the sensor substrate. A Y electrode array having a plurality of electrodes in parallel to each other is disposed on the reverse surface of the sensor substrate in a direction orthogonal to the X electrode array. A first through hole is formed at one end of the X electrode array, while a first land is formed at one end of the Y electrode array. A second land is disposed on the sensor substrate so that it can be electrically connected to the first through hole.
