Abstract:
A photoelectric conversion apparatus includes a photoelectric conversion unit having a light incident surface and including: a first electrode; a second electrode disposed further toward the light incident surface; and a photoelectric conversion layer disposed between the first and second electrodes. The photoelectric conversion apparatus includes a member in contact with the photoelectric conversion layer and constituting a light guide together with the layer. An area of a first surface parallel to the light incident surface at a portion of the photoelectric conversion layer surrounded by the member is smaller than an area of a second surface disposed between the first surface and the second electrode at a portion of the photoelectric conversion layer surrounded by the member, and an area of orthogonal projection to the light incident surface of the first electrode is smaller than an area of orthogonal projection to the light incident surface of the second surface.
