1. A force sensing device comprising:

  • a first insulating layer;

    a first electrode layer on the first insulating layer;

    a second electrode layer provided in opposition to the first electrode layer; and

    an elastic layer held between one or both of the first insulating layer and the first electrode layer, and the second electrode layer, and configured to prevent the first and second electrode layers from coming into contact with each other even while allowing the first and second electrode layers to get close to each other, whereinwhen the first electrode layer or the second electrode layer is pressed, the pressing force is sensed on the basis of a variation in the capacitance between the first electrode layer and the second electrode layer corresponding to a variation in a distance between the first electrode layer and the second electrode layer.
