PURPOSE: An input device for and interface is provided to be configured only by a conductive SUS and an electrode, thereby realizing miniaturization. CONSTITUTION: An input unit includes a SUS, a PCB(Printed Circuit Board), and a plurality of spacers. The SUS is formed on the thin film. On PCB, an electrode(131) and a ground terminal are formed from the center of a circle to be alternated. A signal sensing unit(500) senses an electrode signal due to contact of the SUS and the electrode. A control unit(700) determines an input location of the input unit by a digital signal of the signal sensing unit and receiving time. The control unit outputs input information corresponding to the input location.
