Abstract
A photoelectric conversion apparatus according to one aspect of the present invention includes a first substrate including a photoelectric conversion region and a surrounding region, and a second substrate including a circuit for processing a signal from the photoelectric conversion region, and overlapping the first substrate. In this case, the circuit for processing a signal from the photoelectric conversion region includes a first circuit and a second circuit with a higher drive frequency than that of the first circuit. In an orthogonal projection, the second circuit is only provided in the photoelectric conversion region.
