There is provided an input apparatus including: a pressure detecting unit which detects press pressure of an operational body applied to a virtual key having one or more input candidates allocated selectively; and an input control unit which varies a selection state of the one or more input candidates selectively allocated to the virtual key for every pressing operation having, as a single time of pressing operation, timing that the press pressure detected by the pressure detecting unit exceeds a predetermined selection threshold value or timing that the press pressure becomes smaller than the selection threshold value as being attenuated after exceeding the selection threshold value.
