摘要：
A photoelectric conversion device including: a photoelectric conversion portion having a light absorbing layer (613) disposed between charge injection inhibition layers (611,614) and having a predetermined forbidden band width Eg₁, and a carrier multiplication portion (612) including a single or a plurality of inclined band gap layers, the inclined band gap layer including a minimum forbidden band width Eg₂ and a maximum forbidden band width Eg₃ which are disposed to be in contact with each other to form a hetero junction and having, at the two ends thereof, forbidden band widths Eg₄ which holds a relationship Eg₂
