Abstract
First and second substrates are disposed to face each other and allowed to approach each other. A plurality of first electrodes are formed on the first substrate. A plurality of second electrodes are formed on the second substrate and face the respective first electrodes. A facing electrode pair is constituted by each of the first electrodes and a corresponding one of the second electrodes. A switching unit causes each of the first electrodes and each of the second electrodes to be connected to a driving unit or a detecting unit and switches between a first detection state in which a distance change between each of the first electrodes and a corresponding one of the second electrodes is detected and a second detection state in which the coordinates of a position that an operating body approaches or touches are determined in accordance with detection outputs from the facing electrode pairs.
