摘要： A photoelectric conversion apparatus includes a semiconductor layer having a front surface and a back surface and in which a plurality of photoelectric conversion portions is provided between the front surface and the back surface, a wiring structure arranged on the front surface side of the semiconductor layer, a separation portion arranged between the plurality of photoelectric conversion portions and formed by a trench continuing from the back surface, a first light shielding portion arranged above the semiconductor layer on the back surface side so as to overlap the separation portion, and a second light shielding portion arranged above the semiconductor layer on the back surface side so as to face the first light shielding portion via a region located above at least one photoelectric conversion portion among the plurality of photoelectric conversion portions.
