Abstract: An imaging device includes a pixel electrode having a top surface and a bottom surface facing the top surface, a photoelectric conversion layer that is in contact with the top surface and converts light into electric charge, and a top electrode that faces the top surface of the pixel electrode with the photoelectric conversion layer interposed therebetween. The pixel electrode contains a nitride of a first metal, and a second metal different from the first metal. The nitride of the first metal is a main component of the pixel electrode. A concentration of the second metal in a first three-dimensional region including the top surface is higher than a concentration of the second metal in a second three-dimensional region including the bottom surface. The first three-dimensional region does not include the bottom surface, and the second three-dimensional region does not include the top surface.
