An image sensor includes a substrate having a first surface and a second surface that are opposite to each other. The substrate including a plurality of unit pixel regions having photoelectric conversion regions and floating diffusion regions disposed adjacent to the first surface. A pixel isolation pattern is disposed in the substrate and is configured to define the plurality of unit pixel regions. An interconnection layer is disposed on the first surface of the substrate. The interconnection layer includes a conductive structure having a connection portion that extends parallel to the first surface of the substrate and is spaced apart from the first surface of the substrate. Contacts extend vertically from the connection portion towards the first surface of the substrate. Each of the contacts are spaced apart from each other with the pixel isolation pattern interposed therebetween. The contacts are coupled to the floating diffusion regions, respectively.
