<p>PURPOSE:To provide a coordinate input device which removes influence owing to external noise and precisely detects a coordinate. CONSTITUTION:A coordinate input device where coordinate detection parts (1 and 2) constituted by making an X-axis detection flat body and a Y-axis detection flat body, which are provided with resistances (1R and 2R) and electrodes (1a, 1b, 2a and 2b), face each other is provided, and an X-coordinate value and a Y-coordinate value can be detected from an output value obtained in accordance with an input position from a plane direction as against the coordinate detection parts is provided with a resistance surface 20 (or a conductor surface) insulated from the coordinate detection part on a side near an input surface compared to the coordinate detection part, and the resistance surface or the conductor surface is grounded.</p> |
