1. A touch sensor comprising:

  • a first electrode that comprises a plurality of lines of first resistive films, the plurality of lines of first resistive films being disposed to extend in a first direction and arrayed in a second direction that intersects the first direction, whose end parts in the first direction are electrically connected to each other;

    a first connection pattern for electrically connecting together the end parts in the first direction of the plurality of lines of the first resistive films;

    a second electrode that comprises at least one line of second resistive film disposed opposing the plurality of lines of first resistive films, the second electrode being arranged such that contact surface area between the at least one line of second resistive film and the plurality of lines of first resistive films varies in accordance with a pressing force that narrows a spacing between the plurality of lines of first resistive films and the at least one second resistive film;

    a second connection pattern for electrically connecting the end part in the second direction of the at least one second resistive film; and

    a detection device that, based on a change in a resistance value from the first electrode to the second electrode, detects a contact between the plurality of lines of first resistive films and the at least one line of second resistive film and detects the extent of the contact surface area between the plurality of lines of first resistive films and the at least one line of second resistive film based on a resistance value that is measured by a resistance measuring apparatus connecting to the first connection pattern and the second connection pattern.
