An object of the present invention is to provide a photoelectric conversion apparatus which can enhance photo responsibility. A photoelectric conversion apparatus includes: a photoelectric conversion element configured to output a photo current generated by a photoelectric conversion; a detecting unit configured to detect a potential of an output terminal of the photoelectric conversion element; a feedback input unit configured to input a feedback signal based on the potential detected by the detecting unit; a current detecting unit configured to detect the photo current; and a current amplifier unit configured to generate an amplified current based on the photo current detected by the current detecting unit, and to output the amplified current to the feedback input unit, wherein the feedback input unit outputs a current derived by adding the photo current to the amplified current.
