Abstract
Abstract An image readout element of an image readout sensor for reading image information comprises an insulation substrate which transmits light, a pair of electrodes opposite to each other which are deposited on the substrate, and a photoconductive layer coated on the substrate and the pair of electrodes, the photoconductive layer comprising particles showing photoconductive characteristics and a resin material for dispersing and binding the photoconductive particles. There are provided a plurality of the sensor element in a single image readout sensor, and one of each pair of electrodes is arranged in parallel with one of the other pairs of electrodes.
