PURPOSE:To maintain excellent resolution by providing a guide path leading a lighting light to an original face between a glass base and a transparent protection and leading a reflected light to a photoelectric conversion element to each photoelectric conversion element. CONSTITUTION:A light radiating from a light source 14 radiates an original face 19 through a light guide window 13 and a core part 20 with each picture element, the reflected light is led to a photoelectric conversion element 11, from which electric picture information is obtained. In this case, since the light radiating to the face of the original 19 passes through the core part 20 of the guide path, the diffusion to adjacent picture elements is reduced. Moreover, the quantity of incident stray light made incident with a larger angle than the aperture angle of the guide path in the reflected light from the face of the original 19 is reduced by a scatterer in a clad layer 21. As a result, crosstalk to an adjacent photoelectric conversion element 11 is reduced and the resolution of the image sensor is improved. |
