Photoelectric conversion device and equipment

A photoelectric conversion device comprising:

• a first substrate and a second substrate laminated on one another,
• wherein the first substrate has a pixel region including a photoelectric conversion element for acquiring a pixel signal,
• wherein the second substrate has a processing circuit for (1) processing the pixel signal, (2) obtaining a digital signal, and (3) performing digital signal processing of the digital signal,
• wherein a first wire, which is a wire including a plurality of wire layers and which is a common wire to be connected in common with a plurality of pixels in the pixel region, is arranged,
• wherein a second wire, which is a wire including a plurality of wire layers and which is a wire for supplying a power supply voltage to the processing circuit, is arranged,
• wherein at least a part of a shield wire, which is not to be electrically connected with any of the first wire and the second wire, is arranged between the first wire and the second wire, and
• wherein the shield wire extends from one end to another end opposite thereto of the processing circuit in a plan view of the second substrate.
