  • Patent number: 9354752
    Abstract: A sensor apparatus and an information processing apparatus having excellent operability are provided. A sensor apparatus includes a touch panel, a casing, and a pressure-sensitive sensor. The touch panel includes an input operation surface and detects a position at which an operator comes into contact with the input operation surface directly or indirectly. The casing accommodates the touch panel. The pressure-sensitive sensor includes a first electrode fixed to the touch panel, a second electrode fixed to the casing, and an elastic body arranged between the touch panel and the casing and elastically supporting the touch panel with respect to the casing. The pressure-sensitive sensor detects a pressing force input to the input operation surface, as a change of a capacitance between the first and second electrodes.
