Abstract: Provided are a photoelectric sensor and an electronic device. The photoelectric sensor includes a substrate, a plurality of photoelectric sensing elements, and a wall structure between two adjacent photoelectric sensing elements. The wall structure includes a first layer and a second layer stacked with the first layer. The first layer is arranged at a side of the second layer away from the substrate and includes a light-blocking material. At least one of the first layer or the second layer of the wall structure is arranged in a same layer as at least one layer of the photoelectric sensing element.
