Abstract
A photoelectric conversion device includes a first substrate including a pixel array portion, in which a plurality of photoelectric conversion portions is arranged in a two-dimensional array shape in planar view, and a first wiring pattern, and a second substrate including a machine learning portion configured to perform processing of a signal obtained from electric charge generated by the photoelectric conversion portions and a second wiring pattern, the first substrate and the second substrate being stacked on each other, wherein the first wiring pattern of the first substrate and the second wiring pattern of the second substrate are joined to each other to configure a metal joining portion, wherein a heat dissipation portion including the metal joining portion connected to the machine learning portion is located at a position overlapping the machine learning portion, and wherein the pixel array portion and the machine learning portion do not overlap each other.
