FIELD: physics.
SUBSTANCE: in photo-electric conversion device capable for summation of signals of the photo-electric conversion elements included into the photo-electric conversion units, each of photo-electric conversion elements includes the first semiconductor area of the first type of specific conductivity for collecting of alarm charge, the second semiconductor area of the second type of specific conductivity is placed between the photo-electric conversion elements placed next to each other and included into the photo-electric conversion unit, and the third semiconductor area of the second type of specific conductivity is placed between the photo-electric conversion elements placed next to each other among multiple photo-electric conversion elements and included into the different photo-electric conversion units placed next to each other. Concentration of admixture of the second semiconductor area is lower than the concentration of admixture of the third semiconductor area.
EFFECT: obtaining the required signal by means of use of appropriate insulating structure.
