ABSTRACT:
A photoelectric conversion apparatus includes a pair of opposite electrodes, and an amorphous silicon film. The amorphous silicon film is sandwiched between the pair of opposite electrodes and serves to perform photoelectric conversion of light including light from a target object. At least one of the pair of opposite electrodes is divided into a set of pattern electrodes respectively connected to the amorphous silicon film in electrically positive and negative directions so as to form a spatial filter electrode. The respective pattern electrodes respectively connected in the positive and negative directions are irregularly arranged on the amorphous silicon film.
