Abstract
A photoelectric conversion apparatus having a pixel array region and a peripheral region includes a pixel array, a readout unit, an output unit, a plurality of output lines, and a color filter layer which is arranged in the pixel array region and the peripheral region and includes a color filter arranged above the plurality of pixels. The color filter layer extends to surround the output lines when viewed from a direction perpendicular to a surface of a semiconductor substrate, and has an opening arranged above the plurality of output lines. The opening of the color filter layer is filled with gas or an insulator lower in dielectric constant than the color filter.
