A capacitive touch sensor for detecting a touch point of a user includes a transparent non-conductive base plate, a transparent electrode thin film formed on one surface of the transparent non-conductive base plate, the electrode thin film being formed such that a plurality of polygonal or circular unit cells are connected to other unit cells adjacent in horizontal and vertical directions through signal transmission conductors, and a control board in which the electrode thin film forms a first electrode of a charge capacitor and forms a second electrode of the charge capacitor when the user touches the other surface of the transparent non-conductive base plate such that the control board receives through the conductors a touch signal induced in the first electrode by a user's touch when the user touches the other surface of the transparent base plate as the second electrode and detects a touch point of the user. |
