Sensor apparatus and information processing apparatus

An information processing apparatus, comprising:

• a sensor panel that includes an input operation surface and is configured to detect positional coordinates of a detection object that comes into contact with the input operation surface;
• a casing;
• a pressure-sensitive sensor that includes (a) a first electrode fixed on a sensor panel side, (b) a second electrode fixed on a casing side, and (c) an elastic member between the sensor panel and the casing, the elastic member elastically supporting the sensor panel with respect to the casing, the pressure-sensitive sensor being configured to detect a pressing force that is input to the input operation surface as a change in a capacitance between the first electrode and the second electrode,
• wherein,
• the pressure-sensitive sensor has first and second areas between the first electrode and the second electrode, the first area having a first capacitance and the second area having a second capacitance, the second capacitance being larger than the first capacitance,
• the first and second areas are located along a circumferential region of the sensor panel,
• the second area is located along a center axis of the pressure-sensitive sensor, and
• a display panel is provided on a back side of the sensor panel and accommodated in the casing.
