Abstract

According to one embodiment, a photoelectric conversion device including a substrate having opaque interconnection layers, an insulating film formed on the substrate, and having a plurality of openings, light-emitting elements formed of the openings, each light-emitting element having an upper electrode layer, and light-receiving elements formed of the openings, each light-receiving element having an upper electrode layer, wherein a semiconductor material is different in the light-emitting element and the light-receiving element, the upper electrode layer both of the light-emitting element and the light-receiving element are formed as common electrodes, and each interconnection layer is formed on a region outside a region specified by the opening.

First claim

What is claimed is:

1. A sensor comprising:
light-emitting elements respectively formed in some of a plurality of pixel regions on a substrate, the light-emitting elements irradiating an interior of a living body with light;
light-receiving elements respectively formed in some of remaining pixels of the plurality of pixel regions, the light-receiving elements each comprising:
a sensor light-receiving element receiving the light emitted from the light-emitting element and refle…
