Patent attributes
A photoelectric conversion apparatus having a first substrate and a second substrate overlaid on each other and including electrically conductive portions is provided. The first substrate includes a photoelectric conversion element, a first portion configured to form part of a first surface, a second portion which is included in an electrically conductive pattern closest to the first portion, and a third portion which is included in an electrically conductive pattern second closest to the first portion. The second substrate includes a fourth portion configured to form part of a second surface, and a circuit. In a planar view with respect to the first surface, an area of the first portion is smaller than an area of the second portion and larger than an area of a portion of the third portion overlaying the second portion.
