1. A photoelectric conversion apparatus comprising a plurality of pixels each including a plurality of sub pixels and a micro lens shared by the plurality of sub pixels, wherein each of the plurality of sub pixels includes, in a semiconductor layer of a substrate, a photoelectric conversion portion, a charge holding portion configured to hold charges generated by the photoelectric conversion portion, and a floating diffusion layer configured to convert the charges transferred from the charge holding portion into a voltage, and
wherein at least parts of the charge holding portions and the floating diffusion layers are arranged to overlap each other between adjacent sub pixels among the plurality of pixels in a depth direction of the substrate in a state where a region for separating the at least parts of the charge holding portions and the floating diffusion layers is provided therebetween.
