Provided is an input apparatus that can reduce incorrect inputs and improve the operability. The input apparatus according to an embodiment of the present technology includes a keyboard module and a control circuit. The keyboard module has a plurality of key areas, and a plurality of sensor devices capable of detecting pressures of keystroke operations for the plurality of key areas, respectively. The control circuit that makes a difference between input sensitivity to the keystroke operation of one key area and input sensitivity to the keystroke operation of a key area next to the one key area on the basis of a pressure information item about each of the key areas next to each other, the pressure information item being detected by the keystroke operation on the plurality of sensor devices at the same time.
