Abstract
To provide a configuration including a fully differential amplifier in which decrease in a reading speed can be suppressed. A photoelectric conversion apparatus according to the present invention includes a pixel area where a plurality of pixels are arranged; an amplifier configured to amplify a signal from the pixel area; a plurality of signal paths for transmitting the signals from the pixel area to the amplifier. The amplifier is a fully differential amplifier which includes a plurality of input terminals including a first input terminal and a second input terminal to which the signals from the plurality of signal paths are supplied and a plurality of output terminals including a first output terminal and a second output terminal and the input terminals and the output terminals have no feedback path provided therebetween.
