Abstract: An image sensor includes a substrate including adjacent first and second pixel regions; a photoelectric converter at the substrate; and a pixel isolation portion separating the first and second pixel regions based on penetrating at least a part of the substrate between the first and second pixel regions. The pixel isolation portion includes first and second insulation portions respectively adjacent to the first and second pixel regions, and a conductive layer and an inner layer between the first and second insulation portions and including different materials. The pixel isolation portion includes a first portion including a portion where the conductive layer occupies a space between the first and second insulation portions in an intersection direction that intersects an extension direction of the pixel isolation portion, and a second portion including the conductive layer and the inner layer between the first and second insulation portions in the intersection direction.
