PROBLEM TO BE SOLVED: To provide a two-dimensional(2D) image reader, capable of markedly suppressing wrong reading operations or damages to the device, by suitably discharging electric charges on a body of a photosensor device to be detected. SOLUTION: This 2D image reader has a configuration, provided with a photosensor array 100 having plural photosensors 10 arrayed into a matrix form on one side of an insulated substrate 19, a ground electrode layer 23A provided on a protecting insulating film 20 which is provided for covering the plural photosensors 10 while being directly brought into contact with and placing a body (finger 40) to be detected, and a lead wiring 24 for connecting the ground electrode layer 23A to a ground potential. |
