Abstract
Photoelectric conversion apparatus includes semiconductor layer in which first photoelectric converters are arranged in light-receiving region and second photoelectric converters are arranged in light-shielded region, light-shielding wall arranged above the semiconductor layer and defining apertures respectively corresponding to the first photoelectric converters, and light-shielding film arranged above the semiconductor layer. The light-shielding film includes first portion extending along principal surface of the semiconductor layer to cover the second photoelectric converters. The first portion has lower surface and upper surface. The light-shielding wall includes second portion whose distance from the semiconductor layer is larger than distance between the upper surface and the principal surface. Thickness of the first portion in direction perpendicular to the principal surface is larger than thickness of the second portion in direction parallel to the principal surface.
