A device for performing identification by sensing the fingerprint of a finger includes an input unit. The input unit is constituted by a plurality of linear contact electrodes formed on a substrate, and a pressure-sensitive sheet formed on the linear contact electrodes and a resistance thereof changes in accordance with a pressure applied thereto. When the finger touches the surface of the pressure-sensitive sheet, a change in resistance is caused between the electrodes, and this change is converted to data of a one-dimensional electrical signal distribution. The obtained data is compared with registered data, thereby performing identification. The time required for signal processing necessary in the identification device can be decreased.
