Abstract
In a sandwich type image sensor having a photoelectric converting portion comprising a photoelectric conductive layer interposed between an upper electrode and a lower electrode, a light-shielding means is provided for selectively covering an end portion of the photoelectric conductive layer so as to be excluded from a light-receiving area of the converting portion. Alternatively, an insulating layer partly blocking the contact between the photoelectric conductive layer and the lower electrode is provided for effectively defining the light-receiving area of the converting portion. In an example where the photoelectric is divided so that it is operable as those of a plurality of sensor elements arranged in a row, a light-shielding means is provided for defining light-receiving areas of the sensor elements, while overlapping areas of the upper and lower electrodes are adjusted for equalizing the stray capacitances of the sensor elements inclusive of their connecting portions.
