1. A photoelectric conversion device, comprising:
a substrate;
a photodetection film that includes a first surface facing the substrate and a second surface opposite to the first surface;
a plurality of pixels disposed in a pixel region, each of the plurality of pixels including a first electrode that is provided between the substrate and the photodetection film, and overlaps the photodetection film when viewed from a normal direction of the substrate;
a second electrode that is provided between the substrate and the photodetection film and includes a first portion overlapping the first surface and a second portion not overlapping the first surface when viewed from the normal direction of the substrate, the second electrode being disposed outside the pixel region when viewed from the normal direction of the substrate;
a third electrode that is provided on the second surface of the photodetection film and includes a third surface facing the second surface;
wiring that electrically connects the second electrode and the third electrode; and
a first conductive plug that is connected with the first portion of the second electrode and extends toward the substrate, wherein
material of the first conductive plug is different from material of the second electrode, and
the wiring is in contact with a side surface of the photodetection film and the second portion of the second electrode.
