1. An electrode sheet comprising:

  • a first insulation layer and a second insulation layer; and

    a first electrode and a second electrode which are located between the first insulation layer and the second insulation layer, wherein the first electrode and the second electrode are placed on the first insulation layer and the second insulation layer is placed on the first electrode and the second electrode;

    wherein a capacitance between the first electrode and the second electrode is detected, which is changed according to a relative distance change between the electrode sheet and a reference potential layer spaced apart from the electrode sheet and located within a display module;

    wherein a magnitude of a pressure which causes the distance change is detected according to the change of the capacitance;

    wherein the electrode sheet is attached to a touch input device comprising a substrate and the display module in such a manner as to be attached to any one of a surface of the substrate that faces the display module, and a surface of the display module that faces the substrate;

    wherein the electrode sheet is spaced apart from the display module or the substrate; and

    wherein when the pressure is applied, the display module is bent and the relative distance change between the electrode sheet and the reference potential layer is caused.
