Identification apparatus

Abstract

An identification apparatus includes: a sensor face in which a plurality of sensor electrodes and a ground portion are provided on one and the same plane; wherein: a conductive portion or conductive portions formed in an identification object are configured so that when the identification object is placed on the sensor face, the conductive portion or the conductive portions can electrically connect a corresponding one or corresponding ones of the sensor electrodes with the ground portion; and a change of electrostatic capacitance occurring when the corresponding sensor electrode or electrodes are electrically connected with the ground portion is detected so that an ID of the identification object can be identified. Thus, it is possible to provide an identification apparatus which can be manufactured inexpensively without using expensive devices such as RFIDs and which is improved in terms of the degree of freedom for design.
