Abstract
The device comprises multiple stylus electrodes embedded in a row in an electrode support member, a plurality of common connecting conductive members which are arranged at substantially the same distance from the row of multiple stylus electrodes, parallel to each other with substantially the same distance therebetween, and which are disposed on a curved insulating base plate so that the lead wires for connecting the multiple stylus electrodes to the common connecting conductive members are substantially the same in length. The lead wires are arranged so as to be spaced from each other as far as possible for making uniform the distribution of the capacity of the capacitors formed between the respective lead wires and for reducing the absolute value of the capacity of the capacitors.
