A photodetection device includes a lower structure, one or more common line connecting portions and one or more pixel electrodes provided on the lower structure, an organic photoelectric conversion layer that is provided so as to overlap with the one or more pixel electrodes and not to overlap with the one or more common line connecting portions, and a transparent electrode layer that is provided so as to overlap with the organic photoelectric conversion layer and the one or more common line connecting portion, where a part of the transparent electrode layer that overlaps with the one or more pixel electrodes is thicker than other parts.
