Abstract: A detection device includes a substrate, a plurality of photodiodes arranged on the substrate, a plurality of transistors provided correspondingly to each of the photodiodes, an insulating film that covers the transistors, and a plurality of lower electrodes each of which is provided above the insulating film correspondingly to each of the photodiodes, and is electrically coupled to the transistors. The lower electrodes and the photodiodes are stacked in this order above the insulating film, and one of the lower electrodes and one of the photodiodes are provided so as to overlap the transistors in a plan view from a direction orthogonal to the substrate.
