Abstract:
1. A photoelectric conversion element which is formed by alternately stacking a region of a first conductivity type and a region of a second conductivity type as a conductivity type opposite to the first conductivity type to form a multi-layered structure, in which a plurality of signals are output from junction surfaces between the neighboring regions of the first and second conductivity types comprising: a surface semiconductor region of a conductivity type opposite to a conductivity type of a surface-side region of the junction surface closest to a surface formed in a surface of the surface-side region, said surface semiconductor region not being connected to a wire which is used to output the signals, and wherein concentrations of the stacked region of the first and second conductivity types are designed so that the stacked regions are depleted upon resetting the regions to a predetermined potential.
