ABSTRACT:
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.
