Abstract
A photoelectric conversion element includes: a first photoelectric conversion layer including: a bottom electrode; a photoelectric conversion layer; and a top electrode; and a second photoelectric conversion part including: a bottom electrode; a photoelectric conversion part; and a top electrode. A conductive layer is formed on the bottom electrode. The top electrode and the bottom electrode are electrically connected by a conductive portion and the conductive layer. The conductive portion is formed of a part of the top electrode filled in a first groove that makes a surface of the conductive layer exposed and separates a photoelectric conversion layer and a photoelectric conversion layer from each other. The top electrodes are physically separated by a second groove provided to make a step surface of a stepped portion provided in the photoelectric conversion layer exposed and have a bottom surface thereof overlap the surface of the conductive layer.
