Abstract
An imaging device includes a first substrate, and a second substrate stacked on the first substrate. A first connection portion and a second connection portion are between the first substrate and the second substrate. A first pixel and a second pixel each include a photoelectric converter that converts incident light into a signal charge, and a detection circuit that detects the signal charge. The first substrate includes the photoelectric converter and the detection circuit. The second substrate includes a first line, and a voltage source that is coupled to the detection circuit of the first pixel, via the first line and the first connection portion, and that is coupled to the detection circuit of the second pixel, via the first line and the second connection portion.
