1. An imaging device comprising a plurality of circuits,
wherein the plurality of circuits each comprises:
a plurality of pixels each comprising a circuit configured to generate a first signal and a first operation circuit configured to generate a second signal by multiplying the first signal by a weight coefficient; and
a second operation circuit configured to perform an arithmetic operation using a plurality of second signals output from the plurality of pixels,
wherein the first operation circuit is configured to be supplied with a potential corresponding to the weight coefficient,
wherein the second operation circuit is located below the plurality of pixels, and
wherein in each of the plurality of circuits, the plurality of pixels are directly connected to the second operation circuit.
