Abstract
A contact-type image sensor comprising a light source that illuminates the manuscript to be read; photodetectors that convert the light reflected by the manuscript into an electrical signal; a substrate that is disposed between the photodetectors and the manuscript, a bundle of optical fibers being buried in the substrate; and wiring electrodes that are disposed on the top surface of the substrate corresponding to the light-emitting face of the bundle of optical fibers and that are disposed on the light-receiving surfaces of the photodetectors, wherein the photodetectors are disposed in such a manner that the light-receiving surfaces of the photodetectors face the light-emitting face of the bundle of optical fibers, the wiring electrodes disposed on the photodetectors being electrically bonded to the wiring electrodes disposed on the substrate.
