Abstract: An information input device including a touch panel configured to be provided with a touch sensor that detects a position at which a sensing object is brought close to a sensing surface. In this information input device, the touch sensor has a scanning electrode and a detecting electrode that is opposed to the scanning electrode with the intermediary of a dielectric substance, and is a capacitive sensor whose electrostatic capacitance changes if the sensing object is brought close to the detecting electrode. Furthermore, a slit is formed in a surface of the detecting electrode opposed to the scanning electrode.

Abstract: A sensing unit performs a first sensing process of sensing an approach or a contact of an object to a display panel by collectively sensing electrostatic capacitance of each of a plurality of sensing electrodes provided in a matrix pattern. Further, in a case where the approach or the contact of the object has not been sensed in the first sensing process, the sensing unit repeats the first sensing process, and in a case where the approach or the contact of the object has been sensed in the first sensing process, the sensing unit performs a second sensing process of sensing a position of the object by individually sensing the electrostatic capacitance of each of the plurality of sensing electrodes.
