Claim Text:
1. An input apparatus comprising: a first substrate in which a first resistance film is provided on its one surface; a second substrate in which a second resistance film is provided on its one surface facing the first resistance film; a first pair of electrodes provided on the second resistance film so as to face each other, and provided for applying electric potential distribution to the second resistance film in a first direction; a second pair of electrodes provided on the second resistance film so as to face each other, and provided for applying the electric potential distribution to the second resistance film in a second direction different from the first direction; a reference resistance in which its one end is connectable to the first resistance film and its another end is grounded; a measuring unit configured to measure a difference in electric potential for each of the first direction or the second direction while the electric potential is applied to the second resistance film and the reference resistance is connected to the first resistance film, the difference in electric potential being a difference between a first electric potential of a first end of a contact resistance and a second electric potential of a second end of the contact resistance, the contact resistance being generated when the first resistance film and the second resistance film contact each other; and a detecting unit configured to obtain pressure information indicative of a pressure load caused when the first substrate is pressed based on the difference in electric potential measured by the measuring unit.
