摘要： An image sensor comprises a plurality of photoelectric converting elements of the sandwich type arranged on a substrate in which a photoelectric conversion layer is sandwiched between upper and lower electrodes and a light shielding film having a window for controlling the quantity of incident light is formed so as to correspond to each of the photoelectric converting elements, wherein, noting the fact that a photoelectric current can be dervied from a wider area than the actual area of a photoelectric converting region, an overlapped region of lower and upper electrodes in each of the photoelectric converting elements is made smaller in area than that of the window.

摘要： 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.
