A touch input device capable of detecting a touch pressure in accordance with an embodiment of the present invention may be provided that includes: a reference potential layer; a pressure sensor spaced apart from the reference potential layer; and an intermediate member having at least one through-hole formed therein. Air between the reference potential layer and the pressure sensor flows through the intermediate member via the through-hole. A capacitance detected from the pressure sensor is changed according to a change of a distance between the reference potential layer and the pressure sensor.
