Abstract
An image sensor comprises signal generation unit for generating an image signal on the basis of reflected light using a plurality of photoelectric converters arranged on a substrate, and image forming unit for projecting the reflected light, from an original image, within a predetermined area on the substrate on which the signal generation unit is provided, wherein the signal generation unit includes signal output unit for outputting the image signal from the plurality of photoelectric converters to the outside of the signal generation unit, and a part or all of the signal output unit is arranged outside of the predetermined area on the substrate. Accordingly, reflection of light by the electrodes is prevented, and no light noise incidents on the photoelectric converters. Therefore, it is possible to increase the S/N ratio of the image sensor.
