Patent ID: 8809924

Claim:
An imaging device comprising: a plurality of photoelectric conversion elements that is arranged above a substrate; and a read-out portion that reads out signal corresponding to charges which are generated from each of the photoelectric conversion elements, wherein each of the photoelectric conversion elements comprises: a first electrode that collects the charge; a second electrode that is disposed opposite to the first electrode; a photoelectric conversion layer that generates the charges in response to light incident on the photoelectric conversion layer and disposed between the first electrode and the second electrode; and an electron blocking layer that is disposed between the first electrode and the photoelectric conversion layer, wherein a distance between the first electrodes of adjacent photoelectric conversion elements is 250 nm or smaller, and each of the electron blocking layers has a first face nearer to the first electrode and a second face nearer to the second electrode and has a change in surface potential of −1 to 3 eV from the first face to the second face.
