Abstract
A two-dimensional image reading unit includes a semiconductor layer made of a photoelectric material having a pin structure, a plurality of transparent electrodes aligned parallel to each other and provided on one face of the semiconductor layer, and a plurality of opaque electrodes aligned parallel to each other and provided on the other face of the semiconductor layer such that the opaque electrodes intercept with the transparent electrodes. A photoelectric cell is defined at each crossing point of the transparent and opaque electrodes.
