ABSTRACT:
A hybrid sensor is formed by stacking a plurality of flexible sheets each provided with electrode patterns. The hybrid sensor includes a contact pressure sensor which has switches turning on or off by a pressure load, and an electrostatic capacitance sensor which detects a nearby object without contacting the object. The electrode patterns include a switching electrode pattern as the switch of the contact pressure sensor and a detecting electrode pattern as the detecting electrode of the electrostatic capacitance sensor. The detecting electrode is formed to cover substantially the entire area other than the area on which the switching electrode pattern is formed.
